As you age, you have an increasing chance of having a baby born with a birth defect. Yet most women in their late 30s and early 40s have healthy babies. See your doctor regularly before you even start trying to get pregnant. She will be able to help you prepare your body for pregnancy. She will also be able to tell you about how age can affect pregnancy.
During your pregnancy, seeing your doctor regularly is very important. Because of your age, your doctor will probably suggest some extra tests to check on your baby's health.
More and more women are waiting until they are in their 30s and 40s to have children. While many women of this age have no problems getting pregnant, fertility does decline with age. Women over 40 who don't get pregnant after six months of trying should see their doctors for a fertility evaluation.
Experts define infertility as the inability to become pregnant after trying for one year. If a woman keeps having miscarriages, it's also called infertility. If you think you or your partner may be infertile, talk to your doctor. Doctors are able to help many infertile couples go on to have healthy babies.
