Been 5yrs with boyfriend. why do i always worry that when i marry i would not be able to conceive? normal to worry before even trying to have kids?

Common worry: I think it is natural to have this fear. You try hard during your courtship not to let a baby complicate the process, then wonder if you could if you try. Most couples who want kids can make them, and either partner could be the problem if pregnancy eludes you. If you want, a frank discussion with your doc might clear up some concerns, but until you actually try,you won't know.
