Hello, third trimester!
You're in the home stretch. You'll most likely have a checkup every two weeks until 36 weeks, then switch to once-a-week visits until you deliver.
Pregnancy weight gain
In the third trimester, aim for a steady weight gain of about a pound each week. You need about 450 extra calories per day to support your pregnancy – here are some healthy pregnancy foods and pregnancy snacks to help you meet that goal.
Sex: Yay or nay?
Generally, it's safe to have sex during the third trimester. If you're having a healthy, uncomplicated pregnancy, you can probably continue to have sex right up until your water breaks or you go into labor.

Chores to avoid
At 31 weeks, your nesting urge may be in full force, but it's important to avoid certain chores that can be unsafe – like moving furniture and using strong chemicals.
Healthy pregnancy recipes
Nourishing yourself and your baby is crucial during pregnancy, but it's not always easy. These pregnancy recipes are quick, delicious, and packed with nutrients.

Changing positions
In the next few weeks, your baby will likely get into the ideal position for birth – head down, facing your back. About 97 percent of babies get here on their own – but some end up in different positions.
Able to survive and thrive
At 32 weeks, if you have your baby early their chances of doing well are very good. Called moderately preterm, babies born between 32 and 34 weeks often need care in the NICU, but are unlikely to have lasting problems.
Baby movement
Keep monitoring your baby's kicks, and tell your doctor or midwife immediately if you notice a change. If you’re unsure what's normal, read our guide on baby movements closer to the due date.

More prenatal visits
These days, you may feel like your doctor or midwife has a revolving door. Third-trimester prenatal visits are frequent – and if you're having a high-risk pregnancy, you may see your provider even more often.
What happens after birth
Find out what to expect in the minutes and hours after your baby arrives.
Is that pee?
For most women, the amniotic sac doesn't rupture until right before labor starts, or during labor. But you may want to know what it feels like (and looks like) when your water breaks.
34 weeks pregnant
Keeping tabs on your baby
Your provider will measure your fundal height – the distance from your pubic bone to the top of your uterus – at every visit to estimate your baby's size. If you want to know how fetal growth is expected to progress at this stage, see our breakdown of fetal size by weeks.
Tired of pregnancy?
Carrying a growing baby isn't easy, especially as the end of your pregnancy approaches. If you're bored or tired of being pregnant, know that what you're feeling is completely normal.
Preparing for maternity leave
If you're working, sort out the details of your maternity leave. Talk to your company's HR department, fill out paperwork, and write a transition plan.
35 weeks pregnant
Ready to drop
Soon your baby will drop into your pelvis, giving your lungs more room but putting more pressure on your bladder. This is one way your body's preparing for labor – but it doesn't predict when labor will start.
Late-pregnancy dreams
Hormonal changes plus sleep disturbances can lead to vivid and bizarre dreams in late pregnancy. It's common for pregnant women to dream about their baby, body changes, water, and being in labor.

36 weeks pregnant
Getting in position
Most babies have gotten into position for birth by now, facing your spine with their head down. If your baby is breech (bottom-down), your provider may try to manually turn them by applying pressure to your abdomen.
Weekly prenatal visits
Prenatal visits are more frequent at the end of pregnancy – you'll see your provider once a week until delivery. They'll continue to check your blood pressure, weight, and urine and watch for complications.
If you give birth this week
If your baby arrives at 36 weeks, they'll be considered "late preterm" and will have the same chance of being healthy as full-term infants.
37 weeks pregnant
Labor approaching
You could go into labor at any time – though most women give birth in the two weeks before and after their estimated due date. You'll know you're in labor when your contractions are getting stronger, longer, and more frequent.
Cervix check
Your doctor or midwife may check your cervix to see how much it has effaced (softened and thinned) and dilated (opened).
Almost to the finish line
You're getting close now, but doctors don't consider your baby "full term" until 39 weeks.
38 weeks pregnant
You're almost there!
Most women give birth within two weeks of their due date. Watch for these signs that labor is near.
The nesting instinct
Fueled by bursts of energy, you may find yourself cleaning the nursery and preparing your home. If stress spikes while you prepare, here’s how to relieve stress quickly.
Learn while you wait
While you wait for your baby to arrive, consider taking virtual classes on infant CPR, baby sleep, and physical milestones.
39 weeks pregnant
Congratulations!
Your baby is full term. That means they're fully developed and ready to greet the world.
Staying active
Gentle exercise is okay now, as long as you don't have certain complications. If fatigue is catching up with you, read about managing stress and overwhelm.
Time to induce?
If you're having a healthy pregnancy, your provider may suggest inducing labor at 39 weeks.
40 weeks pregnant
You made it!
Congratulations – you made it to your due date! Your pregnancy is full term and your baby is fully developed and ready to meet you.
How to get labor going
Natural ways to induce labor aren't proven – but walking and sex are low-risk options that may help.
Staying positive
If you're anxious about labor, use grounding exercises or affirmations. If you need emotional support, try Mental Health AI for Female Wellbeing – a gentle, personalized tool designed to help you navigate the emotional side of pregnancy.
41 weeks pregnant
Time for induction?
Your doctor or midwife will recommend inducing labor if your baby isn't born this week. Providers won’t let you go more than two weeks past your due date because it raises the risk of complications.
Meeting your baby
Your baby may look a little funny at first – misshapen head, peeling skin – but that’s all normal after birth.
Sharing the news
Whether you share via text, social media, or something creative, take your time and savor the moment before announcing the arrival.
