This is gonna sound bad but I'm 17 and I'm not pregnant as far as I'm aware, however my partner and I have had unprotected sex from time to time and I never seem to get pregnant, (it's usually around the time I'm most fertile) I don't know what it is, I'm going to have a pelvic X-ray tomorrow, but has anybody else had this?? Like I'm not complaining now, however my partner and I really want to have children in the future, so I don't know if this is going to be a problem.. Please help.
