Trying to conceive !!

Bee

Me and my boyfriend and trying to have baby. I have a three year old, which is not his child biologically, he’s been raising her since she was months old. The first time I got pregnant I wasn’t even aware. Now that i want to. I can’t get pregnant. I haven’t seen a doctor yet because I’d rather just try natural but my boyfriend has ejaculated in me more than enough times. Even while I’m ovulating. Not sure if it’s him or me. (P.s he got his ex gf pregnant years ago but she removed the baby once they found out) So now we think it’s the right time for us. Please let me know if you guys have any tips of tricks !! Also, I’ve never been on birth control.
