In the 1st trimester, a lot happens in your body: hormones quickly shift everything into “pregnancy mode,” and you may start to notice the first symptoms. You might be dealing with emotional ups and downs, mood swings, nausea, and physical discomfort. As unpleasant as it can be, these changes are a sign that a little person is developing inside you. Toward the end of the first 12 weeks of pregnancy, nausea and other symptoms often ease, and your baby will already have reached many important developmental milestones.

Hello, 2nd trimester. Your pregnancy is becoming harder to hide, and your baby bump will grow significantly in the coming weeks. Soon, you’ll be able to feel your baby’s first movements, and your partner will likely find the pregnancy more tangible, too. If you’d like, you can find out your child’s gender during the 2nd trimester.

In the 3rd trimester, everything focuses on growth, and week by week, your baby and your body prepare for birth. For many women, the end of pregnancy can feel uncomfortable—so give yourself as much rest and relaxation as possible whenever you feel exhausted.
