Need help working out who my unborn baby's dad is? My lmp was 23/11/16. I had sex with guy #1 on the 3/12/16 & 9/12/16, he didn't ejaculate inside of me. I had sex with guy #2 on 4/12/16 and the next few days, he ejaculated in me every time we had sex. I probably ovulated on the 7th/8th. who could be my child's father?
