Okay so this morning when I went to use the restroom I urinated; it also hurt badly. Not only that when I wiped myself there was light colored blood. This was the only time that this happend to me. Yesterday I did drink heavily. I am female. I also am sexually active.  I smoke cigarettes and marijuana every now and then. So that isn't normal. What does it mean?
