I was told I concieved on the 4th of Febuary. I am 10wks&3days pregnant. The problem is I had sex with my husband the 30-31 of January. He ejucalated in me. Well I slipped up and had sex with guy number 2 the day after(Feb.5) i supposbly concieved, but he did not ejculate in me, but he did on my backside. Who could be the father? Please help!
