Your baby

Your baby is now ready to be born. They weigh about 3.2kg and measure about 35cm from head to bottom. They may still have some lanugo – fine hair – on their body, but it has mostly disappeared. They are probably covered in vernix, a white, creamy film that protects their skin from amniotic fluid.

The meconium inside your baby’s bowel can sometimes be released during labour. If this happens, it would turn the amniotic fluid green. Your baby would then need to be monitored closely since it could be a sign they are in distress.

How to go into labor 38 weeks

Your body

You could go into labour at any time between now and 42 weeks. You might notice the very early signs of labour, which include pressure in your pelvis, cramps or tightening like period pains, backache or diarrhoea. You might have a ‘show’ – when a plug of mucus comes out of your vagina – or your waters might break, either as a trickle or a gush.

You will know if you are in labour when you have strong, regular contractions that last for at least a minute each.

You are probably feeling tired and uncomfortable, but some women get a burst of energy in the last few weeks of pregnancy. You may feel like you need to prepare the house for the baby. Just be careful not to exert yourself physically.

Things to remember

Every labour is different. Often, labour is very slow and can take hours or days. But sometimes, things can move very quickly.

It’s a good idea to have a plan in place for what to do when labour starts. Your doctor or midwife will have discussed with you when to go to the hospital. It’s a good idea to give the hospital a call when you go into labour.

Make sure you know how you will get to hospital when the time comes. Do not drive yourself. If for some reason you can’t contact your partner or support person, make sure you have another way of getting there.

How to go into labor 38 weeks

Your due date is an educated guess for when your baby might make its arrival.

While many women deliver perfectly healthy babies 2 weeks before or after this presumed due date, it’s recommended that women wait until at least 39 weeks for delivery.

It’s best to let mother nature decide when your baby comes.

In a 2011 study, 201 women who had recently delivered babies were surveyed about inducing labor at home. Of these women, 50 percent had tried a natural method of getting labor started.

If you’re 40 weeks in, here are seven natural ways to get things moving along.

Most of these methods are anecdotal and don’t have solid evidence that they work, so you should always talk to your healthcare provider before attempting any of these methods.

Your midwife or doctor may not be able to confirm that they work, but they can let you know if it’s safe to try with your pregnancy.

Exercise can be anything that gets the heart rate up, such as a long walk. Even if this method doesn’t work, it’s a great way to relieve stress and keep your body strong for the task ahead.

Theoretically, there are multiple reasons why having sex could induce labor.

For example, sexual activity, especially having an orgasm, can release oxytocin, which may help jumpstart uterine contractions.

Also, for pregnant people who have sex with men, there are prostaglandin hormones in semen that might help ripen the cervix.

Having sex is safe during the final weeks of pregnancy, but you shouldn’t have sex after your water has broken. Doing so can increase your risk for infection.

Stimulating your nipples can cause your uterus to contract and may bring about labor.

Nipple stimulations stimulate oxytocin production. Oxytocin is the hormone that causes the uterus to contract and the breast to eject milk.

In fact, if you choose to breastfeed your baby right after delivery, this same stimulation is what will help your uterus shrink back to its original size.

You or your partner may manually stimulate your nipples, or you can try using a breast pump.

Solidresearch shows that breast stimulation can be an effective way to:

  • induce and augment labor
  • avoid a medical induction
  • reduce rates of postpartum hemorrhage

Acupuncture has been used for thousands of years. The exact way that acupuncture works is unclear.

In Chinese Medicine, it’s believed that it balances the chi or vital energy within the body. It might also stimulate changes in hormones or in the nervous system.

Acupuncture should be administered only by a licensed acupuncturist.

In a 2013 randomized trial in Denmark, more than 400 women were given acupuncture, membrane stripping, or both procedures before labor.

Study results showed that acupuncture didn’t decrease the need for induction, but sweeping membranes did.

According to research, the main benefit of acupuncture is increased cervical ripening.

Some practitioners believe that acupressure can help start labor. Prior to applying acupressure to yourself, make sure you get proper instruction from a trained acupressure professional.

If acupressure doesn’t get your labor going, it can still be an excellent way to alleviate pain and discomfort during labor.

Drinking a little bit, like only 1–2 ounces (29.57–59.14 mL) of castor oil stimulates prostaglandin release, which can help ripen the cervix and get labor started.

It’s recommended that this be done under the supervision of a midwife or doctor. People should be careful not to drink too much.

Some research shows that eating dates in the final weeks of pregnancy

  • increases cervical ripening and cervical dilation at the start of labor
  • decreases the need for Pitocin use during labor

Most pregnant people at 40 weeks are likely ready to have their babies out of their bellies as soon as possible and in their arms.

However, there are plenty of perks to waiting until your body naturally decides to go into labor — including recovery.

Women who weren’t induced typically recover more quickly than those who were. More time in the womb can mean both you and your new baby get to go home from the hospital sooner.

Infants who are born after a full-term pregnancy also experience other benefits. More time in the womb typically means:

  • more time to build muscle and strength
  • reduced risk of low blood sugar, infection, and jaundice
  • improved breathing as infants born even as little as two weeks early can experience twice the number of complications
  • better feeding once born
  • increased brain development, with the brain growing a third of its size between weeks 35 and 40

Let your body do the work for a few more days and take the time to get as much rest as you possibly can.

We know, that’s easier said than done when you’re 9 months pregnant. You and your baby will need all your energy soon enough!

Before trying anything that might induce labor, speak with your healthcare provider to go over any risks or possible complications.

Though some of these methods are popular folklore among pregnant women, little scientific evidence supports their efficacy.

In most cases, it’s best to let baby set their own birth date, even if it means waiting another week or two.

How likely is it to go into labor at 38 weeks?

26 percent of births occur at 37 to 38 weeks. About 7 percent of births occur at weeks 34 to 36. About 6.5 percent of births occur at week 41 or later. About 3 percent of births occur before 34 weeks of pregnancy.

What triggers labor to start?

Researchers now believe that when a baby is ready for life outside his mother's uterus, his body releases a tiny amount of a substance that signals the mother's hormones to begin labor (Condon, Jeyasuria, Faust, & Mendelson, 2004). In most cases, your labor will begin only when both your body and your baby are ready.
