Ask the OB-GYNs: FAQs About Pregnancy

Laura Donnelly, MD, and Erin DuMontier, MD, are back with another installment of 'Ask the OB-GYNs.' This week they discuss some commonly asked questions they receive about pregnancy.


When should I be worried that I haven't gotten pregnant when trying?

“Infertility is when a woman has not gotten pregnant after twelve months of regular, unprotected intercourse,” Dr. Donnelly explains. “At this point, if you haven’t achieved a pregnancy you should make an appointment with your physician. Other factors to including in your evaluation are if you are 35 or older, you should seek evaluation if you have not become pregnant after six months. Additionally, if you are not having regular menstrual cycles you should see a physician at any time.”

Can I exercise during pregnancy?

“Safe forms of exercise during pregnancy are recommended and encouraged,” Dr. Donnelly says. “Exercise during pregnancy can help reduce the risk of gestational diabetes, help with back pain, increase your energy, improve your mood, and help your endurance during labor. Safe forms of exercise are walking, running, cycling, swimming and aerobics. Exercise that has a high risk of falling or risk of abdominal trauma should be avoided.”


What is a miscarriage?

“The loss of a pregnancy prior to 20 weeks is called an early pregnancy loss or miscarriage,” Dr. DuMontier explains. “Miscarriages are surprisingly common and occur in up to 15 to 25 percent of known pregnancies."

What causes a miscarriage?

"Most miscarriages are caused by a random event in which the embryo receives an abnormal number of chromosomes or genetic material," Dr. DuMontier says. "The sperm and egg cells each have 23 chromosomes. During fertilization, when the egg and sperm join, the two sets of chromosomes come together to make a total of 46. An embryo with an abnormal number of chromosomes often cannot grow or survive and may result in a miscarriage.”
