My stomach has been bloating for 4 days now after sex .... and I've have been so anxious and stressed out, because I think I might be pregnant.

On May 5th, my period stopped, I had (unprotected) "sex" on the 6th of May. I'm not sure if I'm still a virgin, but my boyfriend had his penis rub onto my vagina, and I can't remember if there was any precum near my vagina. Now heres the other stupid thing I did.... I can't remember, but he cummed on my stomach and I think my hand accidentally made contact with the semen (on my stomach) , and I started to finger myself (I'm unsure on what hand I used....) but I believed before I did any fingering, when I made contact with the semen, I think my boyfriend wiped my hand with his (sweater) before I did anything... but we were unsure, so he pored water on my vagina and wipped it with his boxers... So now I'm just clueless, scared to know the fact if I'm pregnant or not, I'm praying to god, and hopeing I'm not. So I talked to my boyfriend on the phone he said that his doctor told him can't really have babies,unless he really tried. He would actually have to cum multiple times inside me to actually get me pregnant. Does that seem right?
