How Long Were You Nauseous Before Labor? (Early Signs & Causes)

Nausea appears on almost every list of early labor signs out there. So, if you’re more than 38 weeks pregnant and start feeling sick, it’s tempting to think you’re just a day away from newborn cuddles.

Unfortunately, while some women do experience nausea before labor, many more feel sick for other reasons. A few of these could leave you nauseous for weeks.

Is Nausea an Early Sign of Labor?

Nausea in your third trimester could be an early sign of labor. If it’s accompanied by diarrhea and the loss of your mucous plug, you could be just 24 to 48 hours away.

However, before you get too excited, labor isn’t the only cause of late pregnancy nausea. Here’s a list of the potential culprits:

Labor

When labor is imminent, your digestion will shut down, so your body can focus on giving birth. If you have a full stomach, this could trigger nausea or vomiting. Diarrhea is common too. Oh, the glamour of birth!

Hormones

Your levels of the hormone progesterone will peak around 32 weeks. This is great for your pregnancy as it prevents pre-term labor. Unfortunately, it also relaxes your bowel muscles, slows digestion, and triggers nausea.

Anxiety

Stress or worries about your impending labor could cause you to feel a little queasy. Try relaxation techniques or talk to your healthcare provider about your fears.

Prenatal Vitamins

If you’ve recently changed supplements, this could be the source of your sickness. Ones with high iron are particularly bad for nausea. Talk to your doctor about switching to something that won’t upset your stomach.

Lack of Space

As your baby grows, your uterus expands and puts pressure on your stomach and intestines. This can cause heartburn for 60%, nausea for 16%, and vomiting for 7% of women in their third trimester.

Vomiting Bug

If you have absolutely terrible timing, you might pick up a vomiting bug in your third trimester. This is more likely if you know someone else who’s been sick or you have a fever. Fortunately, it should pass on its own. But, if you can’t keep any liquids down, seek help. Dehydration can trigger pre-term labor and could complicate your birth.

Pre-Eclampsia

Pre-Eclampsia is a high blood pressure condition that affects around 1 in every 25 pregnancies. Symptoms include nausea, vomiting, headaches, changes in vision, pain in the upper stomach, and swelling of the face and hands. The condition requires medical care, so seek help if you have these symptoms.

HELLP Syndrome

Hemolysis, elevated liver enzymes, and low platelet count, or HELLP syndrome, is a rare liver and blood clotting disorder. It affects less than 1% of births and usually appears between 32 and 34 weeks. Symptoms to look out for are pain in the upper right chest area, vomiting, nausea, headaches, and visual disturbances. This condition requires urgent medical care.

Liver Issues

Very rarely (1 in 20,000 pregnancies), nausea could be a sign of Acute Fatty Liver of Pregnancy or AFLP. The key symptoms are vomiting, abdominal pain, and jaundice. It’s considered an emergency. So seek medical help if you suspect this is the cause of your sickness.

The most important thing is to listen to your body. If you feel something is wrong, arrange a blood pressure check and urine test. These are quick and simple, and your healthcare provider will be happy to put your mind at ease.

How Long Does Nausea Last Before Labor?

If your nausea is a symptom of early labor, it may resolve as soon as your stomach is empty. However, you could also feel sick or even throw up throughout your delivery.

Unfortunately, nausea is not a great indicator that your baby will arrive any time soon. It could stick around for weeks if issues like a lack of space or hormones trigger it.

Sickness related to a medical condition should resolve with treatment.

What to Do if You Experience Late Stage Nausea

If you experience nausea or vomiting during your third trimester, you already know what to do. It’s time to revisit your morning sickness coping strategies.

Things that can be helpful include:

• Eating little and often.
• Staying hydrated with water.
• Drinking ginger tea or eating ginger cookies.
• Peppermint oil aromatherapy.
• Avoiding acidic, fatty, or spicy foods that could trigger heartburn.
• Adjusting your prenatal vitamins. Changing the timing, splitting the dose, or switching to a gummy could all help.

If you’ve tried everything and you’re still struggling with nausea, visit your doctor. There are a few different anti-sickness medications that you can take during pregnancy.

How to Treat Vomiting in the Third Trimester

If your nausea progresses to vomiting and you struggle to keep fluids down, seek medical help. Dehydration in your pregnancy could lower amniotic fluid levels or trigger pre-term labor. Both of which could result in complications for your baby.

A doctor can prescribe an antiemetic, or IV fluids.

How to Treat Nausea and Vomiting During Labor

It’s also common for women to vomit throughout active labor. In some cases, it’s triggered by contractions or hormones. But it can also be a side effect of pain medications.

It’s not usually an emergency but could cause you to become drowsy or dizzy. Not an ideal state for giving birth.

Try to maintain hydration throughout your labor. Do this by drinking small sips of water or sucking on ice chips or ice lollies. Your stomach will absorb small amounts even if you feel like you are bringing it all back up.

Also, try to eat or drink something to keep your energy levels up. Yogurt, toast, or muesli bars will help fill your stomach and could relieve your nausea.

Diluted apple or pear juice will also boost you without being too acidic if you can’t handle solid food.

FAQs

Can Labor Cause Nausea?

Yes, lots of women experience nausea during labor and many vomit. This can be due to your body clearing your stomach, the intensity of contractions, or anxiety. It might even be a side effect of pain relief.

Can Labor Start With Nausea?

Yes, nausea could be your first sign of impending labor. But it’s just as likely due to hormones or your baby squashing your bowels. Wait until you’ve experienced a more reliable sign before getting too excited. These include losing your mucous plug, lower back pain, and your waters breaking.

The First, Second & Third Stages of Labour

The three stages of labour explained

Labour is the physical process you go through when giving birth to your little one. During labour your uterus contracts and your cervix opens, which allows your baby to come out into the world for the first time. Although everyone’s experience of labour is different and no one can predict how long it will last, there are three key stages that all women go through.

The first stage of labour consists of the early, active and transitional phases – during these different phases contractions make your cervix gradually open up (dilate) to a full 10 centimetres.

The second stage of labour is the pushing stage, when you’re fully dilated and you’re ready to give birth to your baby.

The third stage of labour is when you deliver your placenta.

First stage of labour

The first stage of labour is the longest and can last for quite a few hours, especially if it’s your first baby.

Possible signs of labour

During the early stages of labour, you may experience the following:

• Feeling sick or nauseous. 
• Tightening of your tummy. 
• An urge to go to the loo – this is because your little one’s head is pressing on your bowel and/or bladder.  
• Lower tummy or back pain – like period pain. 
• Diarrhoea.
• Contractions. 
• Your waters breaking.

For many women, the earliest sign of labour is a cramping feeling – a bit like period pains. You may also have a bit of pain in your lower tummy or back. It’s also very common to experience diarrhoea or to feel sick or nauseous.

 If you are in any doubt about whether or not you think you are going into labour, call your maternity unit. Don’t worry, they are there to help and would rather you and your little one were safe and happy.

During these early stages of labour you may not feel like eating very much, but it’s a good idea to have a snack or a light meal like soup, cereal or toast to keep your energy levels up. Remember to drink plenty of water to keep yourself hydrated too.

The feelings of discomfort may not seem like anything unusual at first, but if you are in labour they will gradually develop into more regular and intense pains, otherwise known as contractions.

How many centimetres dilated should you be in the early stages of labour?

The extent to which your cervix has opened (dilated) is one way that your midwife and doctor can track how far into labour you are. Although this can vary in each pregnancy, here is a general guide:

• Early/latent Labour Phase
  From the onset of painful contractions, although they may be irregular, until the cervix is dilated to 4 cm.
• Established Labour Phase
  From 4 cm until the cervix is open to 7 cm.
• Transitional Labour Phase
  This really can vary. Some women don’t really experience this while others enter it once they are 10 cm dilated.

Getting your show

A plug of mucus has been sealing your cervix while you’ve been carrying your little one. Although this doesn’t sound particularly nice, the mucus plug is your body’s natural way of protecting your uterus and your baby from any unwanted bacteria that could enter your body (which could happen during sex or during your regular pregnancy examinations).

When the mucus plug comes away it is known as ‘a show’ or ‘showing’ and means your cervix is starting to change and open. This means your body is getting ready to welcome your little one to the world. Sometimes women experience a show a few days or even a couple of weeks before labour begins and it’s a sign of things beginning to happen.

Not all women get a show in the early stages, so don’t worry if you don’t have one. Your plug will come out naturally at some stage during your labour.

Waters breaking

During your pregnancy your baby has been growing and developing in a bag of fluid called the amniotic sac, which surrounds and protects your baby. This is commonly known as your ‘waters’. When you are in labour, your waters will ‘go’ or ‘break’, but the timing of this will vary for everyone. For some women, their waters might break early, but for others it may not be until you’re in active labour. Some describe the release of fluid as a trickle, others as a gush. Some babies are also born in the amniotic sac.

If you’re a little unsure about whether or not your waters have broken, amniotic fluid is clear and a pale straw colour. It’s normal for the water to be a little bloodstained to begin with. Vaginal discharge can increase greatly towards the end of your pregnancy, and it can therefore be really hard to tell the difference between discharge and waters. If in doubt put a pad in place and call your maternity unit.

If your waters break in the early stages of labour the risk of infection is increased, so it’s very important to keep your vaginal area very clean. Don’t use tampons, have sex or any hot baths.

Contractions

As you near the end of your pregnancy, you’ll probably begin to question every little tummy twinge, bowel movement or Braxton Hicks. This can be particularly true if it’s your first baby. Don’t worry, it’s perfectly natural to question every little movement.

So what is a contraction and what do they feel like? Contractions are a tightening and relaxing of the muscles in your uterus, which you may feel in the front or back, and they’ll feel stronger than the irregular Braxton Hicks you may have experienced during pregnancy.

If you’re in labour, you’ll start to experience contractions at increasingly shorter intervals, and they’ll become longer and stronger in intensity.

Contractions are not continuous and can be irregular. This is to allow you, your baby and your uterus to have a little rest after each one.

How to time your contractions

To help monitor the progress of your labour it’s important to start timing your contractions once they get going. One of the main reasons for this is that when you call your maternity unit to tell them you’re in labour, one of the first things they will ask is how often you are contracting.

To time your contractions, try and count the seconds between each one. If you’re able to use a clock or stopwatch, or better still, get your birth partner to help, this will ensure you’re monitoring them correctly. It’s often easier to note down the time each contraction started and how long it lasts for. You can then count the time between each one. This also helps to show if they are regular.

A typical pattern for your early phase contractions is for them to begin by lasting about 40 seconds and come every 10 minutes. By the time you’re ready to give birth, the contractions will last about a minute and come every 2 minutes. These timings are just a guide, and they’ll vary from person to person.

What is slow labour?

Everyone’s different and not all labours stick to a timetable! A slow labour is quite common and nothing to worry about. But if things slow down too much, it might be necessary to speed them up a bit.

Slow labour signs

Slow labour is sometimes defined as when the cervix dilates less than 0.5 cm per hour over four hours. Your midwife will be aware that you’re showing slow labour signs and will know what to do. Remember, you’re in safe hands, and your midwife will be able to answer any questions you might have. The National Institute for Health and Care Excellence (NICE) guidelines state that women should dilate 0.5 cm each hour (2 cm over 4 hours) in established labour (from 4cm)¹. If delay in the first stage is noted, you may be referred to an obstetrician.

Second stage of labour

The second stage of labour begins when your cervix is 10 cm dilated and ends with the birth of your baby.

If this is your first baby, the second stage may still take an hour or even longer to complete. But if you’ve had one or more babies already, it can take as little as five minutes.

Pushing your baby out

Your body will tell you when to push – in fact, the urge will probably be overwhelming and pretty difficult to resist!

Once your baby’s head is visible, your midwife may encourage you to try and slow the process down by asking you to stop pushing and pant instead. It’s a delicate stage and this is important, as it may help reduce the risk of tearing. You’ll gently push your baby out on the next contraction.

At last your baby will be born. You’ll probably be encouraged to have skin-to-skin contact (if you choose to) at this point and you can finally say hello to your baby.

Third stage of labour

It might seem odd that you’ve still got another stage of labour to go after your baby has been born, but there is still a bit of work left to do – delivering the placenta. Don’t worry, your midwife will stay with you and guide you through it.

Delivering the placenta

Your midwife will offer you an injection to help with the delivery of the placenta. If you choose to have the injection, delivery will probably happen within 30 minutes. But if you decide to deliver naturally, it may take up to an hour.

You’ll find that the contractions will start again, enabling you to gently push your placenta down and out of your vagina.

Once it’s delivered, your midwife will feel your tummy to check that your uterus has started to contract now the placenta has gone. The placenta will then be checked thoroughly to make sure that it is complete.

Breastfeeding straight after birth

If you asked for skin-to-skin contact after birth, your midwife will probably encourage you to try to breastfeed straight away. This allows you to spend some special time and bond with your little baby.

Harbingers of childbirth in nulliparous | Signs of the onset of labor during the first pregnancy

Expectant mothers should carefully and carefully treat their body and the signs that it gives. There are signs that may appear a few days or even weeks before the onset of labor. Many women take them very seriously, but it is important to understand that not a single harbinger is a 100% sign, but only indirectly reflects the changes taking place in the body of the expectant mother, not being a signal to rush “at full speed” to the hospital.

The expectant mother lost weight

The hormonal background during pregnancy changes greatly, in particular, the production of progesterone increases significantly. This hormone is necessary for the development of the fetus, and when the child’s body is almost formed, its concentration begins to fall. A side effect of progesterone is water retention in the body. Therefore, when the production of progesterone decreases, as a result, there is a decrease in swelling of body tissues. Such changes can be quantified in the form of a loss of body weight of the expectant mother, and these losses can reach one or two kilograms.

Why is this harbinger of childbirth considered indirect? Firstly, the dynamics of body weight depends on many factors, not only on the hormonal background. Secondly, each organism is individual, and in some women, weight loss before childbirth is not observed. Thirdly, weight loss does not specify in any way the expected date of the birth of the child – labor can begin both in the coming days and in 2-3 weeks.

The baby began to move less. This is due to the fact that he has grown up and he no longer has enough space in the uterus for “acrobatic studies.” In contrast to such changes in the behavior of the baby, in some cases, the approach of childbirth may be accompanied by an increase in the intensity of fetal movement.

In any case, this sign only says “soon”, but cannot indicate a date on the calendar. It is also important to understand that the prenatal decrease in the activity of the child is an event in the last month of pregnancy. If you notice such symptoms at an earlier date, these are not harbingers of childbirth, and it would be useful not to leave this without attention and consultation with a specialist.

Abdominal prolapse has occurred

The most well-known sign of an imminent onset of labor is abdominal prolapse and this is due to a change in the position that the baby takes at the end of pregnancy, preparing for childbirth. In primiparas, abdominal prolapse usually appears two weeks before the baby’s birthday. In women who have given birth before, it usually falls later, sometimes it happens just before the onset of labor. But there are other examples when the belly of the future mother drops a few weeks before the planned date. In other words, after the onset of this symptom, there may be hours before delivery, or maybe weeks – and no one can say for sure.

When the belly sank, the expectant mother feels relief: the upper part of the uterus descends, thereby reducing the pressure on her lungs and stomach, and it becomes easier for the woman to breathe. At the same time, she develops a “duck” gait characteristic of late pregnancy: these changes in the posture of the expectant mother are also associated with the prolapse of the uterus and the preparation of the baby for childbirth.

The pregnant woman began to run to the toilet more often

Some pregnant women notice an increase in the frequency of urination, which, as a rule, is caused by compression of the pelvic organs by the fetal bladder. Frequent urination is not a separate harbinger of childbirth, but only a consequence of uterine prolapse and is not a sign of their imminent onset.

The expectant mother has diarrhea

But this may be a sign of the imminent start of labor. The fact is that in the process of preparing for labor, the mechanism of relaxation of the smooth muscles of the uterus is launched. It does not have a selective effect and at the same time relaxes the muscles of the intestine.

Diarrhea starts 1-2 days before delivery and resolves without any other symptoms. If, along with a loosening of the stool, the expectant mother has signs of intoxication, for example, vomiting or fever, most likely this is a common poisoning. In this case, it will not be superfluous to consult a specialist leading your pregnancy.

The mucus plug has come off

Another sign of imminent labor is the separation of the mucus plug. It is a clot of mucus, with a volume of 2-3 ml, not much denser than daily vaginal discharge, colorless or with a small amount of blood streaks. If the vaginal discharge has a different volume, density, color, or a higher blood content, this is a signal to immediately contact a specialist!

Many future mothers consider the discharge of the mucous plug as the surest sign of the onset of labor, but this is not entirely true. The body does not send any special commands to reject it, it falls out on its own when the birth canal has expanded enough, and this can happen at any time. Often after this event, a woman has a few more days before the baby is born, and sometimes the cork leaves already in the process of childbirth. During the second pregnancy, this harbinger may deceive expectations and appear earlier or later than during the first.

What are the exact signs of the onset of labor?

There are only two sure signs of the onset of labor – contractions and outpouring of water, and these events can occur in any order. Each of them serves as an immediate signal to go to the hospital!

Contractions have begun

Harbingers of childbirth as a measure of time before the onset of labor always raises a lot of questions among primiparas, since many sensations are not easy to understand and distinguish if you have not felt them before.

With contractions, the situation is even more complicated – in addition to true contractions, there are training contractions, the appearance of which is only one of the signs of an imminent birth. During training bouts, the muscles of the uterus “warm up and warm up”, such contractions are not regular, long and not painful.

True contractions are much more painful than training ones, they are not stopped by breathing exercises, they are regular, their duration and frequency are steadily increasing. If all three conditions are met, it’s time to go to the hospital!

Water breaks

We have all seen how water breaks in pregnant women more than once in the plots of popular films. As a rule, with a normal pregnancy and a healthy baby, such discharge is a consequence of the fact that the lower part of the fetal bladder has exfoliated from the uterine wall. And this is another natural and natural stage of mother’s preparation for the upcoming birth. In this case, it is important for the expectant mother and those around her to remain calm and be attentive – note the exact time, evaluate the amount and color of the water – these data can be useful to doctors.

After these simple steps, call an ambulance and wait for it with a pre-assembled “mom’s suitcase” and, most importantly, with all the necessary documents. Now only a few hours left to wait for a miracle!

How long will it take for me to give birth after the onset of labor?

The reference point is the rupture of amniotic fluid or contractions – one of these events that happened earlier. After that, before the birth of a child, primiparas usually have 9 to 11 hours left, and those who give birth again – 6-8 hours. These standards may vary in one direction or another. There is very little left! In just a few days, for the first time, you will take in your arms and hug to your chest the best, charming and beloved baby in the world!

Harbingers of childbirth

Skip to content

Childbirth at term never begins suddenly for a woman, which is especially afraid of nulliparous pregnant women. The beginning of regular labor activity is preceded by the harbingers of childbirth, which prepare the expectant mother for the birth of the baby and remind her of the imminent birth. And although the harbingers are necessarily manifested by certain signs, some women may not notice them.

How does the body prepare for childbirth?

Aging placenta

The placenta, which produces hormones, plays a leading role in preparing the body for childbirth. From the 36th week, the ratio of secreted hormones changes: the production of progesterone, which is responsible for relaxing the smooth muscles of the uterus and prolonging pregnancy, decreases, and estrogens begin to be synthesized in greater quantities. Estrogens trigger the formation of uterine contractile proteins, due to which the susceptibility of myometrial cells to stimulation increases. In addition, high levels of estrogen increase the amount of prostaglandins in the uterus, which, in turn, trigger the release of oxytocin in the maternal and fetal pituitary glands.
Maturity of the cervix
The “maturity” of the cervix can be fairly accurately determined by vaginal examination. The process of “maturation” is due to the following mechanisms, during pregnancy in the cervix there is a gradual partial replacement of muscle tissue with connective tissue. Changes are observed in the cervical connective tissue itself: “young” collagen fibers are formed, which are extremely hydrophilic and therefore more flexible than collagen fibers outside of pregnancy. Clinically, this is manifested by loosening and shortening of the cervix, gaping of the lumen of the cervical canal.

Descent of the uterus
Descent of the uterus usually occurs in primiparas a few days before the onset of labor (in multiparous it occurs a couple of hours or with the onset of regular contractions). This symptom is due to pressing the head to the entrance to the small pelvis, which is explained by the adoption of the fetus in the most convenient position by the beginning of the contractions. People around usually say to a woman: “Oh, your stomach has dropped.” She feels it, as it becomes easier for her to breathe. In addition, expectant mothers note that in recent weeks they could eat quite a bit at one meal, and now it has become possible to “eat properly”. This is due to the fact that the descending uterus stops squeezing the stomach and diaphragm, so it becomes easier to breathe and eat.
The lowered and pressed head of the child, in turn, puts pressure on the rectum and bladder, which is manifested by increased urination and the urge to defecate.

Changes in well-being and mood
Shortly before the birth, the expectant mother may feel drowsiness, some apathy and a desire to retire from the noisy world. This is partly due to the inability to move easily and quickly, with a general change in state. But part of it depends on how the brain works. Gradually, the dominant of pregnancy turns into the dominant of childbirth, the body adjusts to a difficult stage, the woman is completely immersed in her own experiences. For the same reason, nervousness and tearfulness may appear, especially if family members underestimate the degree of anxiety of the pregnant woman.

Fetal movement
When the uterus becomes too tight for the growing fetus, its range of motion is reduced. This leads to hormonal changes in the mother’s body before childbirth. Therefore, a week before an important event, the baby, as it were, “calms down”. This happens often, but not always. In addition, a sharp decrease in activity may indicate oxygen starvation of the child, which is the reason for an immediate visit to the doctor. A similar harbinger of childbirth before 37 weeks rarely appears.

Weight loss
Before giving birth, almost all pregnant women notice a decrease or stabilization of weight, by 0.5-2 kg. This weight loss can be explained by the removal of excess fluid from the body under the influence of changes in the hormonal background. The mother-to-be may notice that gloves and rings are easier to put on, the shoes become less tight and it becomes easier for her to put on shoes.

Nesting instinct
If you conduct a survey among young mothers on the topic “what were you doing when the birth began?”, then very many will probably give similar answers. Pasting wallpaper, dismantling the wardrobe, washing the tiles in the bathroom – these are a few of the things that a woman decides to do at the end of her pregnancy. Such “arrangement of the nest” is akin to the instincts of many animals, when before the appearance of offspring, you need to take care of the home. If such chores do not tire the expectant mother too much, then they should be treated positively. After all, homework is a little distracting from the anxieties and worries about the upcoming birth.

False contractions
The notorious Braxton-Hicks (false) contractions are a frequent occurrence in the last weeks of pregnancy, a harbinger of childbirth in most women. One they can cause discomfort, others do not even realize that there are uterine contractions. The essence of such contractions is to prepare the myometrium for childbirth and the maturation of the cervix. Such contractions do not lead to the opening of the uterine os and are felt as a hardening of the abdomen in response to movement or physical exertion. False contractions are characterized by irregularity, low intensity, painlessness and periods of rest between them up to 30 minutes or more. False contractions occur about 4-6 times a day, usually in the mornings and evenings, and last no more than two hours in a row.

Removal of the mucous plug
This harbinger of labor can occur 2 weeks before the onset of labor, and a few hours before it begins. In some cases, the mucous plug does not come off entirely, but in small portions. In practice, this sign looks like a discharge of vaginal discharge (sometimes mixed with a small amount of blood). A pregnant woman should inform her obstetrician-gynecologist about the discharge of the mucous plug.

When is it necessary to call an ambulance or go to the maternity hospital?
• If the waters break
• If a large amount of blood is excreted along with the water or mucous plug
• Regular labor activity develops 2-3 contractions in 10 minutes
• If the contractions are so strong that they do not allow rest
• Headache occurs , flies before the eyes, blurred vision
• Absence of fetal movements for 6 or more hours
