Blood in stool

I’m quite nervous, I have a doctors appointment on Monday. But it has only happened twice. And its right after I finished. There’s no pain, no other symptoms. I asked my mom, she thinks I’m pregnant. (I have never done anal, so that’s out of the question). But I doubt I can be pregnant. I always use protection. The condoms never seemed to rip. Or at least not that I know of. My boyfriend would not sabotage it either, because he knows I’m not ready for a kid. I guess this is more of a rant than asking anything. I really just need some comfort. I feel so drained from over thinking. My anxiety is getting to me.. (Yes I’m over 18, I know there’s consequences with sex, protection or not, just don’t attack me.. I had enough...)
