Okay so I have a friend that I have sex with sometimes. We had sex without a condom on July 21st. He says he pulled out and came on my butt but I felt something warm go down my butt crack and he wiped off what was on top of my butt etc. I started working out kind of hard core 3 days ago and feel very bloated and just tired and can barely breath normally. I also have back pain but not sure why. I have had diarrhea for the past two days. Is there any chance I could be pregnant? Really scared. If I ever had a child rn my parents would kill me.
