Im so confused idk what to even call this lol

So I made a post the other day about how while having sex we smelt a fishy smell and there was a small trace of blood. Well anyways, last night I woke up to pee and when I wiped there was blood. It’s not heavy enough to be my period but it’s also not light enough to just think nothing of it. I have no cramps and I’m supposed to start in a week. What could this be?.. I wore a pad all night and all day so far and no blood. It’s ONLY when I wipe. Also, the smell isn’t as bad anymore. I never ever spot between periods and am never late or early either. I’m always regular and really need some insight
