So annoyed! Yes I had sex the last day of my cycle(10/8/15-10/11/15) which it was off & the week I ovluted I had sex with another guy whom is my high school ex it was our first time having sex 10/17/15  and a couple days after ovulation was when the baby was conceived which was 10/22/15. I haven't touched or had sex with anyone besides my unborn child father.. I keep track of everything I do in case of situations like these! Besides my bd saying it's his grandma and mom that won't the dna my mom is also doubtful and it's so annoying bc I'm like dude stop arguing with me I know who my child father is and it's really getting to me bc so much of it makes me go back and look myself and once more I'm right!!! So my question is it can't be the guy I had sex with on the last day of my cycle right??? Bc a week after I had sex with another guy then bam November came and I missed my period.. The doctors and other sources also say that the baby was conceived on 10/22/14 based on my last cycle.. And one nurse said that it was odd for me to even be pregnant bc he was conceived 1-3 days after ovulation!!! So anyone that has my due date July 14,2016 or anyone could you please help me clarify or is my mom right???
