THis might be silly but I just need to know if there’s still a chance... so I may 26+2 days pregnant me and my ex broke up over a year ago but was still having a sexual relationship we were having sex regularly up until the end of April And had sex once in may I had a one night stand on the 9th may and the last time with my ex was around the 13th. Midwives have measured baby and put my due date at the 30th jan and put my Lmp as the 25th April so add to weeks onto that my conception date works out to Be the 9th may obviously I know it’s probably the one night stands baby cos that’s the exact date i had sex with him but is there ANY chance at all it could be my ex’s?
