I had been having relationship troubles for a few months being on and off with my partner. We had ended things and I ended up sleeping with someone else on a drunken night out and then almost a week later I got back with my partner. I am now pregnant.
The first day of my last period was the 15th Feb, I slept with guy#1 on the 19th, he did not cum at all as we were both drunk and he was too drunk too maintain his erection, and we ended up just falling asleep. I then got back with my partner, guy#2 and slept with him on the 24th and later again on the 28th, which he had came inside me both times.
Using an online due date calculator it would suggest I would be due 22 Nov, and that I would have ovulated on 1st March, making guy #2 the dad.
However after my 12 week scan, they have said my due date is the 18th Nov and that I must have ovulated earlier with a 24 day cycle, meaning that my conception date would be the 25th Feb.
Is there chance that guy #1 could be the dad even though he didn't come at all?
I am aware of my actions not a hard time about being a slut, etc. Any help or advice would be greatly appreciated.
