Conception date shows the 9th. i had sex with possible father on that date the day before as well as the day after. i had sex with another man on the 12th and he pulled out. is it possible for the first man to be the father?

Fertilization has a window. Not sure when you ovulated, but it usually occurs 14 days before a missed period. Sperm can live for upto five days working their way towards your fallopian tubes. Pull out method is not a form of contraception. If your ovulation date was anywhere between the 8th and the 13th, either one can be the father. You may need a paternity test.
