Hello, I’m female 25yrs, 5’3 130lbs, on and off for the past few months when I use the toilet, there is bright red blood from my anus. Sometimes it’s mucusy. It’s not only when I have a bowel movement. Sometimes my anus will bleed bright red blood when I pee too. I tried eatting more fiber, eatting less fiber, drinking more water, it’s totally random. It’s not painful. What’s causing this?
