Unexpected pregnancy

Heyy y’all. I’m in a situation where I am pregnant but I had 2 sex partners and I am worried.

Partner 1: after a recent break up I met a guy around early November and we were talking getting to know each other and he came by to stay the night, originally we were not supposed to have sex but we began drinking and it happened. We didn’t have sex for long and it was with a condom and he did not cum but the condom did get stuck inside me towards the end (literally only went for 5-10 minutes before I got uncomfortable) this was November 19 and I got my period literally the next day because it’s due around the 20th anyway.

Partner 2: my ex boyfriend and broke up for a couple of months but we ended up working things out and I stopped talking to the other guy and I regularly started having sex with my boyfriend again the day after my slip up with the new dude and more after my cycle around normal ovulation. I went to the doctor when I was a day late (the 21st of December) and got a negative but I tested positive today. l going to take the ethical steps in this situation but I was wondering if I could still be pregnant by the new dude even tho I got my cycle right after we had sex? I was thinking this could be my boyfriends baby because not only did I just test positive which make it a more recent conception date, but I also had unprotected sex with him around my ovulation date after my period ended but I also know crazy things happen still
