Your Second Trimester

Weeks 13-27

Welcome to your second trimester! Right about now your energy should be coming back. Many women feel great at this stage — don’t be surprised if people tell you you’re glowing!  If you find yourself too busy to make it to the office, utilize our VIP OB home visit services!

Weeks 13-16

Your baby

Is almost the size of a plum.
Long, thin arms are growing.
Your little one’s tiny hands can make a fist.
Eyelids are formed and closed, to protect developing eyes.

Your baby has more muscle tissue and harder, more developed bones. Skin is beginning to form, but it is almost transparent at this point. Your little one is starting to roll, kick, and move around a lot — flexing tiny arms and legs, too.

Your body

Your baby bump might be starting to show, and your clothes may be getting a little snug. Hopefully, you’re feeling good and have more energy and less morning sickness than you did in your first trimester. For some women, it takes a bit longer to feel better.

You might not have an appointment with us during these 4 weeks. If your pregnancy is progressing normally, we’ll want to see you between weeks 16 and 20 to see how things are moving along.

Your to-do list

  • If you work, start thinking about when you plan to go on maternity leave. Talk to your employer about your company’s maternity policy and other benefits.

  • Keep wearing your seat belt, even as your belly expands. Stay comfy by placing the lap band below your baby bump.

  • Try to find 10 minutes to relax every single day. Growing a baby is hard work!

Weeks 17-20

Your baby

Is almost the size of a pear.
His or her eyes can move slightly from side to side.
Your little one is starting to develop body fat.
Tiny knees, elbows, and knuckles can bend, flex, and move.

Your body

Can you feel your baby moving? Those first flutters are called “quickening,” and some women say they feel like butterflies.

Don’t panic if you notice dark patches on your face. They’re from the extra estrogen your body is producing and should disappear after pregnancy. Just be sure to use sunscreen to prevent the patches from darkening in the sun. (Actually, sunscreen’s always a good idea.) You may also see a narrow, dark line running from your belly button to the top of your pubic bone. All of these changes are normal signs that your pregnancy is on track.

Your to do list

Schedule an appointment with us between weeks 16 and 20. We’ll measure your baby’s growth and development and get a better sense of your due date.
Decide whether you and your partner want to consult with our professional Birth Doula, Lisa Seaman, LAc.
Prepare for delivery day by taking a tour of your delivering hospital.
If you plan to go back to work, start thinking about child care.

Weeks 21-24

Your baby

Is the size of a pomegranate and weighs close to 11 ounces.
Taste buds have developed, and your little one can swallow.
The taste of the amniotic fluid he or she swallows depends on the food you eat.
Your little one sleeps a lot — around 12 to 14 hours out of every 24.

Your baby is still small enough to change position a lot — from head down to feet down, or even sideways. Although it might not feel like it to you, your baby sleeps long hours, about 12 to 14 hours every day. Oh — and that funny, jerking motion you’ve been feeling means your baby has the hiccups.

Your body

Hormones are causing your joints to soften to get ready for childbirth, which means you may be feeling a little clumsy. Just roll with it!

As your baby kicks and stretches more, anything goes. Seeing your baby squirming under your clothes might feel weird, but it’s actually kind of amazing. It’s also a sign that your baby’s development is on track. Think of it as a high five!

If you have leg cramps, heartburn, insomnia, and other discomforts, we have tips for relief. Our best advice? Take it easy when you can. Remember, growing a baby takes a lot of energy.

To do list

Remember to stay hydrated. It can help ease — and even prevent — common pregnancy symptoms like constipation, headaches, and fatigue.
Make time to connect with your partner. If possible, take a “babymoon” — a weekend away to relax before your new baby comes.
Listen to your body. Get extra sleep when you’re tired — you’ve earned it.

Weeks 21-27

Your baby
At this stage, your baby is over 13 inches and weighs almost 2 pounds, about the size of a papaya. As you get closer to your due date, your baby’s hearing and sense of touch will continue to develop. The eyes will begin to open and close, after being shut tight since way back in your first trimester.

Your body

You’ve had a pregnant belly for a while, but this is the stage when you’ll get a pregnant belly button. As your baby needs more and more room, your uterus will start pushing your abdomen out, and your navel will start popping out. It may look funny, but it’s harmless and temporary. Your belly button will go back to normal a few months after your baby is born.

Feeling like you can’t catch your breath? It’s just your growing uterus pressing on your diaphragm and crowding your lungs. You’ll feel better as soon as your baby settles down into your pelvis and your body starts preparing for childbirth.

To do list:

  • Keep taking your prenatal vitamins to make sure your growing baby gets all the nutrients he or she needs.

  • Learn the signs of preterm labor:

    • Regular contractions for an hour. This means about 4 or more in 20 minutes, or about 8 or more within 1 hour, even after you have had a glass of water and are resting.

    • Leaking or gushing of fluid from your vagina. You may notice that it is pink or reddish. This is called a rupture of membranes, also known as your water breaking. When this happens before contractions start, it's called premature rupture of membranes, or PROM. When it happens before 37 weeks of pregnancy, it is called preterm premature rupture of membranes, or pPROM.

    • Pain that feels like menstrual cramps, with or without diarrhea.

    • A feeling of pressure in your pelvis or lower belly.

    • A dull ache in your lower back, pelvic area, lower belly, or thighs that doesn't go away.

    • Not feeling well, including having a fever you can't explain and being overly tired. Your belly may hurt when you press on it.

If your contractions stop, they may have been Braxton Hicks contractions. These are a sometimes uncomfortable—but not painful—tightening of the uterus. They are like practice contractions. But sometimes it can be hard to tell the difference.
