Probably paranoid 🙄😐

I’m 18 years old and I do know it would be to early to tell. I’m just paranoid probably; but I want to say 3 days ago my boyfriend and I were having sex before I had to take a shower and get ready for work. I’m not on any kind of birth control because my insurance/Medicaid was recently canceled and I haven’t had time to renew it and we had also ran out of condoms... Well he ended up accidentally didn’t pull out in time and nutted in me... this also happen one more time that night after work when we laid down to go to bed. He went to pull out and didn’t make it all the way out in time.. Well starting last night I starting getting the poops, not Diarrhea or constipation I just have to poop about every hour to hour and a half... I also felt nauseous every time I would burp or fart yesterday and noticed I was bloated lastnight. I told my boyfriend about it and he asked me if I was pregnant. I told him it was way to early to be having signs but I wanted to see if anybody else had signs this early. I doubt it but I’m trying to keep it on the safe side even though it seems like it’s to late for that lol..
