The goal of prenatal care is to help you and your baby stay healthy during your pregnancy. During the third trimester, you may have prenatal care visits about every 2 to 4 weeks. Timing depends on your health and pregnancy history. Starting at 36 weeks, you'll likely need checkups every 1 to 2 weeks until you deliver.

At your visits during the third trimester, your healthcare team might ask if you have any symptoms such as contractions and fluid leaks or bleeding. Your team checks your blood pressure and weight and your baby's heartbeat and movements.

Keep track of how often you feel the baby move every day. Let your healthcare team know if the baby stops moving as much. Your baby's movements might slow as you get closer to your due date. Check once a day that your baby moves at least 10 times in two hours. This is called fetal kick counts.

Also, talk to your healthcare team about vaccinations you need. These might include flu, COVID-19 and respiratory syncytial virus (RSV) shots. Another suggested vaccination is tetanus toxoid, reduced diphtheria toxoid and acellular pertussis (Tdap). It's best to get the Tdap vaccine between 27 and 36 weeks of pregnancy.

Expect to be tested for group B streptococcus (GBS) during the third trimester. GBS is a common germ found in the intestines and lower genital tract. It's most often harmless in adults. But babies who become infected with GBS during vaginal delivery can get very sick.

To check for GBS, a member of your healthcare team swabs your lower vagina and anal area. Some people take their own GBS swab after their healthcare team tells them how to do it.

The sample goes to a lab for testing. If the sample is positive for GBS, or if you've already had a baby who got GBS disease, you'll get antibiotics through a vein during labor. The antibiotics help protect your baby.

Near the end of pregnancy, your healthcare team checks to see if your baby is lying head down in the uterus.

Some babies lie rump first, called frank breech, or feet first, called footling breech. Some babies' legs are crossed over their bellies. This is called complete breech. If your baby is in a breech position after week 36 of pregnancy, it's not likely that the baby will move to a headfirst position before labor.

A member of your healthcare team might press on your belly to move the baby to a headfirst position. This is called external cephalic version. This most often is done in the labor and delivery unit using ultrasound as a guide. If you don't want this procedure, or if your baby stays in a breech position, your healthcare team will likely discuss planning a C-section delivery.

You likely have lots of questions as you near your due date. Is it OK to have sex? How will I know when I'm in labor? What's the best way to manage any pain? Should I make a birth plan?

Talk to your care team about all the questions you have. Knowing the answers can help calm you before delivery.

Be sure to ask members of your healthcare team about when you should call them, such as if you have vaginal bleeding or fluid leaking from the vagina. Also ask how to contact the team once labor begins.

You'll be asked if you have any signs or symptoms, including contractions and leakage of fluid or bleeding. Your health care provider will check your blood pressure and weight gain, as well as your baby's heartbeat and movements.

Your health care provider might ask you to track of how often you feel the baby move on a daily basis — and to alert your health care team if the baby stops moving as much as usual.

Also, talk to your health care provider about any vaccinations you might need, including the flu shot and the tetanus toxoid, reduced diphtheria toxoid and acellular pertussis (Tdap) vaccine. Ideally, the Tdap vaccine should be given between 27 and 36 weeks of pregnancy.
