Hi, so me and my boyfriend fool around quite frequently. A couple weeks ago, we were making out and I ended up giving him a blowjob. he did ejaculate, and I swallowed all of it. He wiped off with a blanket and we took a nap. A couple days later, he came over and was rubbing his penis in between my butt cheeks no ejaculation. THEN, yesterday, I gave him another blowjob, he came, wiped off his penis and then put it in between my butt again. I also MIGHT HAVE scratched myself down there from time to time but I think I would've known if sperm were on my hands. My stomach is in complete cramps and I've been tired and burping a lot .. Could I be pregnant?
