I had sex with some1 on sept 6th n a diff person sept 29th my lmp is sept 7th n my due date is june 14 who has a higher chance of being the father?

See below: If you had sex with someone on 9/6 and started your period on 9/7, that person cannot be the father of your baby if that is the only sexual encounter. The 9/29 sex would have been on d22 of your cycle, which is more than a week passed your predicted ovulation. I'm betting on 9/29, but you should see your doctor, confirm your dates and go from there.
