Lately I've been having small amounts of mucus in my stool, I didn't let it bother me because the amount was insignificant, however, today when I went to wipe, a huge amount of white and yellow mucus appeared attached to fecal matter. There was literally more mucus than anything else. I has a very foul odor. And now I'm concerned. If it helps any, about two weeks ago while my boyfriend and I were having intercourse we had an accident and his penis forced into my backside, the pain was unbearable and I cried for about five minute. Maybe thats what caused this? Thank you.
