HELP.

Okay. So my boyfriend and I are trying to have another baby. We've had unprotected sex every day for 2 weeks and he has came in me every time. eve says my period is 6 days late. The thing is, I was on the depo for 3 years . I got it at my 6 week check up. (After having my son may 2013) and I just recently got off in June 2016. I still haven't had my period. Anyways, last night after he came in me I think all his sperm just fell out. Is that normal? Or am I just tripping over nothing. Lol
