I am a female, i don't think i can have children. is something wrong?

Trying for pregnancy: If you are thirty-six, and have had regular intercourse but no pregnancy, it's time to talk with your health care provider. It can be more difficult to become/carry a pregnancy as we get older. Additionally, women are born with all the eggs we will ever have - while men make brand new sperm even when they are older. Btw, most doctors would want to get a semen examination from the man also.
