Sperm can live inside you for up to a week. It could be either guys. No one on here can tell you whose it is. It's to close together.
Did the due date of October 18 come from your earliest ultrasound? It would tend to favor the first guy if so. If it came from a later ultrasound, did your ultrasound person give you a due date when you had the earliest one?
My due date was set as October 18th
this is a difficualt question indeed but u must take into consideration that a week is a bit too small time to know the difference about the time that u get pregnant. In my opinion a prediction will be probablly wrong so the better you have to do it's to wait until you reach the 6th month that u can take blood from the baby for a DNA test.
So guy2 must be the father .... the dates measure up to u slept the guy number two during ur ovulation day ,..... which that dont sta
Rt till 14 weeks befa ur period
What estimated due date did they give you when you had the ultrasound at 6w4d?
