How fertile are you after getting off birth control (pills)? I've heard 10% will be preg after one month off, 20 after 2 and so forth, but wouldn't it be dependent on how long you were on BC to start with?
Also, what about miscarriage rates? Logically the longer you're pregnant, the more likely you are to have a full term child, but is there any chart on probability anywhere?
(Sorry to bore some of you, I'll have something more interesting later...)
