But staying healthy during pregnancy depends on you, so it’s crucial to arm yourself with information about the many ways to keep you and your baby as healthy as possible.

Prenatal Health Care

Key to protecting the health of your child is to get regular prenatal care. If you think you’re pregnant, call your health care provider to schedule an appointment. You should schedule your first examination as soon as you think that you are pregnant.

At this first visit, your health care provider likely do a pregnancy test, and will figure out how many weeks pregnant you are based on a physical examination and the date of your last period. He or she will also use this information to predict your delivery date (however, an ultrasound performed sometime during your pregnancy will help to verify that date).

If you’re healthy and there are no complicating risk factors, most health care providers will want to see you:

• every 4 weeks until the 28th week of pregnancy
• then every 2 weeks until 36 weeks
• then once a week until delivery

Throughout your pregnancy, your health care provider will check your weight and blood pressure while also checking the growth and development of your baby (by doing things like feeling your abdomen, listening for the fetal heartbeat starting during the second trimester, and measuring your belly). During the span of your pregnancy, you’ll also have prenatal tests, including blood, urine, and cervical tests, and probably at least one ultrasound.

If you still need to choose a health care provider to counsel and treat you during your pregnancy, there are several options:

• obstetricians/gynecologists (also known as OB/GYNs — doctors who specialize in pregnancy and childbirth, as well as women’s health care)
• family practitioners (doctors who provide a range of services for patients of all ages — in some cases, this includes obstetrical care)
• certified nurse-midwives (advanced practice nurses specializing in women’s health care needs, including prenatal care, labor and delivery, and postpartum care for uncomplicated pregnancies; there are also other kinds of midwives, but you should look for one with formal training who’s been certified in the field)

Any of these is a good choice if you’re healthy and there’s no reason to anticipate complications with your pregnancy and delivery. However, nurse-midwives do need to have a doctor available for the delivery in case an unexpected problem arises or a cesarean section (C-section) has to be performed.
