I am a trans male, (I used to be a female, and still have the downstairs parts) I've been on hormones for a year and a half (at least) I sometimes get a period every 2-4 months. I've been having sex with my boyfriend, and he has a large amount of pre-cum, and I know he jacks off quite a bit. we've also been trying to get pregnant before my bottom surgery, how do I know whether or not I may be pregnant?
