I'm only asking this question because on March 11th I lost my little Alexander as he was born sleeping (I new two days before that was going to happen) however now nearly 4 months later we are ready to try for our third baby as the first time we miscarried and the second was born sleeping, and we have had sex once last week however since then he's not been able to keep his erection and thier for not being able to complete the deal, he says he wants to try for a third baby however I am wondering if he physically wants to however phycologically he doesn't want to as he's scared of loosing another baby!

I was wondering if that one time last week was enough to get me pregnant?
