Okay so first off I’m 12 weeks pregnant found out back in November and doctor said I would have conceived on the 21st. So I slept with my ex husband one night on September 18th after a funeral and then I went on a date back on October 21st. I stayed the whole weekend with this man and yes we slept together but it wasn’t the first time. Anyways my question is he is saying he is not the father of my baby because my due date is July 14th and I would have to have gotten pregnant on October 7th but my doctor said I would have conceived on the 21st I’m so confused please help me figure out if he is not the father or not 😢😢😢
