Ok, this may be a weird question, but I'm kind of worried. Since last night, when I poop, I bleed. I'm bleeding from my rectum, and today it was so bad that there were drops of blood in the toilet. I don't bleed during the day, it only bleeds when I poop. I thought it was my period at first, but it's not. I need real information - is it just that I'm like, torn, there, or is this a sign of cancer or something?
