Your baby is 15.7 inches long and weighs 2.9 pounds this week. That’s about the size of a bike helmet.

Your Baby’s Development at 30 Weeks

  • Weight gain: Your baby will be putting on half a pound a week for the next 10 weeks!
  • Kick counts: As baby grows, their movements may start to change. You’re still doing your kick counts, right? Do your kick counts around the same time every day (try for when your baby is typically most active), and record baby’s movements and how long it took to reach 10 of them. You’ll begin to notice a pattern of what’s normal for your baby. If you notice less movement—or none at all—call your healthcare provider.
  • Lungs: This week your baby’s lungs are getting stronger in preparation for their first breath.

You have only 10 weeks left, mama!

Pregnancy Symptoms at 30 Weeks

  • Heartburn: In the third trimester, heartburn comes back because your uterus is pushing up on your stomach. (Oh hello, old friend…) Remember to eat smaller meals, and wait to lie down for an hour after eating and avoid greasy foods.
  • Mood swings: Feeling like Jekyll and Hyde? Mood swings are very common in pregnancy because you might be stressed out about your impending life change, and your hormones are off the charts. Remember to go easy on yourself and don’t take on too much, whenever possible. Try to do things that make you feel good, whether it’s going for a walk, spending times with friends or taking a nap.
  • Sleep: At 30 weeks pregnant, sleeping may be difficult. That burst of energy you may have felt during your second trimester might be on the wane. If you’re having trouble sleeping, pregnancy pillows can your friend. Keep the room dark, ditch the screens before bed and try to keep your bedtime consistent.

Your 30 Weeks Pregnant Belly

Typical weight gain at 30 weeks pregnant is about 18 to 25 pounds total. Sticking with about a pound per week, you’ll probably gain 10 or so more pounds by the time you hit your due date.

If your healthcare provider measures fundal height (the distance from the pubic bone to the top of the uterus) at this week’s appointment, it should measure about 28 to 32 centimeters. You may start to feel your uterus grow so your belly extends past your rib cage.

What is Amniotic Fluid?

You know your baby has been floating around in amniotic fluid all this time, but what the heck is it—and what does it do?

Amniotic fluid is the clear or slightly yellowish liquid that fills the amniotic sac in your womb (aka uterus aka cradle of life), acting as a cushion to protect your baby and keep them the perfect temperature. It’s also the liquid that leaks, gushes or you barely notice when your water breaks and you go into labor.

As your baby continues to grow, the amniotic fluid also helps with their development—particularly their lungs and digestive system as they begin to breathe and swallow (yep, they’re breathing and swallowing fluid!).

What’s amniotic fluid made out of? In the early weeks of your pregnancy, the amniotic sac develops in your uterus and begins to fill with fluid, mostly made up of water from your body. By around 20 weeks pregnant, when baby’s kidneys are functioning pretty well, that fluid will be made up mostly of…baby pee. It sounds kind of gross, but, hey, pregnancy and giving birth are filled with all kinds of crazy bodily functions.

If you have an amniocentesis, this is the liquid that’s drawn out to analyze for different forms of birth defects, since, aside from baby’s urine, it also contains some of baby’s cells.

How much amniotic fluid is there? At 30 weeks pregnant, you’re almost at the peak of how much amniotic fluid you’ll produce. You’ll top off at around 1 quart—this is where some of that weight gain is coming from!—and at around 36 weeks, your amniotic fluid will begin to decrease until your baby is born.

When you get your get your ultrasounds, the technician will check to see if your amniotic fluid levels are too low, too high or just about right. If they’re too high, it’s called polyhydramnios, and it’s pretty rare. If the fluid levels are too low, it’s known as oligohydramnios, which occurs in about 4 percent of pregnancies. In either case, your healthcare provider will work with you to help treat the conditions.

Top Tip for 30 Weeks Pregnant

At 30 weeks pregnant, check in with your HR department and get a maternity leave checklist of everything you will need to provide and who you will need to provide it to in order to qualify for leave coverage.

Partner Tip

Taking parental leave too? Do the above at your workplace so you’re squared away, as well.

OB Appointments in Your Third Trimester

You and your OB now seeing a lot of each other. Your prenatal appointments get more frequent during the third trimester. At 30 weeks pregnant, you’re now probably seeing your healthcare provider every other week to make sure baby is developing fine, and there aren’t any complications. This will continue until about 36 weeks pregnant.

After that, you’ll be on a weekly appointment schedule until your baby’s arrival. Of course, if you have any complications or issues with your pregnancy, you may be seeing your healthcare provider more frequently.

During the appointments, your doctor or midwife will check on baby’s growth, measuring your belly from the top of your uterus to your pubic bone—known as fundal height—to see if baby’s growth is on track. They’ll also check baby’s heartbeat.

Now’s the time to let your healthcare provider know if you’re having any new issues or experiencing any contractions. This is also a good time to ask any questions you have about your labor and discuss your birth plan and give them a copy.

Fun Fact

About 4 million babies are born in the US every year.

Maternity Leave

Way back in the first trimester we discussed how to tell work you’re pregnant, but now comes the harder part: actually preparing for leave.

First the paperwork.

Does your employer cover part or all of your salary during maternity leave? Do you live in a state that covers it through official parental leave or short-term disability? Congratulations! When you are bonding with your baby during that tender time, this can be a huge relief. If you have only state coverage or only work coverage, there will still be a lot of paperwork. If you have neither, try to put your financial worries aside in those weeks with your babe before you head back.

Fair warning: you will be filling out a bazillion duplicate forms for everyone and their mother/insurance company. This week, check in with your HR department about a leave checklist of everything you will need to provide and who you will need to provide it to.

Here’s one example of how paperwork might play out. It’s very unlikely that this is exactly your situation. (It was our Editor in Chief’s scenario when she had her first baby.)

You will be filling out a bazillion duplicate forms for everyone and their mother/insurance company.

Let’s say you live in California (which covers maternity leave for six weeks for up to 60 percent of your pay), and your company pays your entire salary for 12 weeks. Great! For part of that coverage, your company pays your wages through their short-term disability insurance, as well as through your regular payroll.

To get paid for those full 12 weeks, you’d have to fill out the paperwork for:

  • State of California’s Employment Development Department (imagine how fun that is)
  • Your employer’s insurance company
  • Your company’s HR to declare that you did, in fact, have a baby

Of course, you can’t fill out these forms in advance because you need details like the baby’s real birth date, sometimes their Social Security number and oftentimes hospital verification.

If your HR department doesn’t have a checklist, talk to a coworker who has recently gone through the process and find out what they needed.

Remember that your leave belongs to you.

Now back to your actual job.

To help you and your team feel prepared, consider creating a maternity-leave plan with what you will do before you leave, what coverage you’ve lined up while you’re gone and your back-to-work transition timeline. Fairygodboss has a useful template to use.

Remember that your leave belongs to you. Turn off your email. Put your work laptop in a locked drawer and give your best friend the key.
