the only guarantee to establishing paternity will be a paternity test. with that said based on a due date of november 20th sex most likely occurred during the period february 22 - february 27. your question was: mine? your sexual encounter of february 5th is out of the range for being the father.
she is due nov. 20th she concieved feb. 26th i had sex with her feb. 5th but she said she had sex with 2 others. mine? . i had sex with a woman feb. 5th and she tells me her doctor told her she conceived feb. 26th. she told me she had sex with 2 other men around the conception date. should i be worried since i had sex with her 3 weeks before her conception date? she also told me she had sex with 2 other men around that time. i pulled out other wore a condom but the third came inside. could i still be the father?
