I had sex with my boyfriend on a day I was fertile. He ejaculated inside me and continued to lay there about 15-20 minutes on top of me while still inside. Two days later I had sex with another guy, but he didn't ejaculate inside me. He pulled out an ejaculated, then wiped it off and we started having sex again a few minutes after that, but he never ejaculated inside me. Who's the father? I'm 18 weeks pregnant.
