Hey everyone! I'd really like to get some opinions here because I feel like I'll be judged by my doctor. My ex and i were together almost 2yrs. The last time we had sex that I know for sure was Oct 17th. I had spotting and an odd period around Oct 22nd. After that we went out the night before Halloween, I got wasted and don't even remember going home. He never said we had sex and i didn't ask, so if we did it would've technically been Oct 31st. So I had sex with someone else Nov 9th and 11th. My period was due around the 19th and obviously never came. On Dec 14th my baby measured 7w2d on ultrasound. In your opinion is my ex the father and i just don't remember conceiving? It's driving me nuts.
