Pregnancy Q & A

How often do I need to see the doctor while I'm pregnant?

Having regular checkups during pregnancy is the best way to ensure mothers and babies stay healthy. After the initial check-up, office visits are usually scheduled a month apart until week 28, at which time they occur every two weeks. At week 36, visits occur weekly until delivery.

What happens during a pregnancy checkup?

Pregnancy checkups begin with a discussion of any symptoms patients may be experiencing, followed by measurements of weight and blood pressure. The belly may also be measured, and depending on how far the pregnancy has progressed, the baby's heartbeat will be evaluated and an ultrasound may be performed. Urine tests and blood work may also be performed. Based on the results of the exam, women will be provided with information on what to expect until the next office visit as well as guidance on staying healthy.

How can I tell if I need a C-section?

Cesarean sections are more common among women with high-risk pregnancies where vaginal delivery may be too risky or may not be possible, such as when a baby is very large or when the mother has an active infection in the birth canal when she goes into labor. Some C-sections are planned in advance of delivery while others may need to be performed on an emergency basis.

Can I have a vaginal delivery if I've had a C-section?

Yes, many women have a vaginal birth after a C-section (VBAC). During pregnancy, frequent evaluations will help determine if vaginal delivery is feasible.

What is a high-risk pregnancy?

High-risk pregnancies are those in which the health of the mother or baby or both is compromised during pregnancy or delivery. Common causes of high-risk pregnancies include:

  • Smoking
  • Being overweight or obese
  • Alcohol or drug use
  • Having hypertension or diabetes, either before pregnancy or developing during pregnancy
  • Older age
  • Having had several prior miscarriages
  • Being pregnant with more than one baby
  • Presence of certain diseases or genetic conditions

Women with high-risk pregnancies usually need to be seen more often to ensure they and their babies stay healthy.
