Third Trimester

What You Need to Know
You will likely visit your health care provider every 2 weeks. Then visits will increase to once a week in your last month. This is the time to ask questions about labor and childbirth. Also, learn the warning signs of preterm labor, and know when to call your health care provider.

Third Trimester Tests
During the third trimester, your blood tests may be done again. You may also have glucose testing at this time. If you are Rh negative, talk to your health care provider at 28 weeks about having a RhoGam injection. This medication prevents Rh antibodies from forming.

Special Concerns
Preeclampsia can occur in any pregnant woman. But if you've had it before, you have a greater chance of it recurring. Also, if you already had high blood pressure before getting pregnant, your risk for preeclampsia is higher. African Americans, teens, women over 40, and women pregnant with two or more babies are also at greater risk.

Postpartum Depression Assessment
Having a baby is a life-changing event, so it’s completely normal to feel a bit overwhelmed. However, if your spirits are down despite your new bundle of joy, it may be a sign of postpartum depression. Take our online assessment to help determine your risk.
