Week 20 pregnancy symptoms

During week 20 of pregnancy, your body is changing quickly. As your baby grows, you will too, and there are certain pregnancy symptoms you may experience at this time.

11 common week 20 pregnancy symptoms

  • Your hair and nails may be experiencing a growth spurt of their own, due to the wonders that are pregnancy hormones.
  • The second trimester is smooth sailing for morning sickness, but that doesn’t mean you won’t struggle with indigestion and pregnancy heartburn.
  • Swelling and edema are common at this point.
  • Your uterus is expanding and can push up against your lungs, making you feel short of breath.
  • Your sleep may be getting disturbed. A few basic changes can help improve your sleep during pregnancy.
  • Rising hormone levels can cause an increase in vaginal discharge.
  • At 20 weeks, your baby bump should now be visible.
  • Your expanding bump may cause your belly skin to itch.
  • You may feel butterflies in your belly as you start to experience “quickening,” the fluttery sensation of your baby wiggling in your uterus.
  • Your appetite may be increasing. Those hunger pangs are a sign of your growing baby’s nourishment needs.
  • You’ll be continuing to gain weight while pregnant.

3 expert tips for a healthy and safe pregnancy

Being 20 weeks pregnant is an important time for you and your baby. Here’s some more expert-recommended advice on how to adjust to this new stage and keep you and your baby safe.

  1. Pumping up the iron: Your iron supply is probably depleted now. As anemia is common when pregnant, you should switch up your diet with iron-rich food or consider taking a supplement.
  2. Everything is in order: If you haven’t had it yet, the mid-pregnancy check-up will allow your OB to check that everything is in order—and if you want to know, it can reveal your child’s gender.
  3. What's up, doc: 20 weeks pregnant is an excellent time to start interviewing pediatricians. Ask friends, family, and coworkers for referrals. Then, set up consultation appointments. Some topics to cover: the office’s hours of operation, hospital affiliation, and resources for new parents. For more questions to consider asking, check out "Finding a Pediatrician".
