I ended my period on Friday October 5th. I am sexually active and did have sex that Friday night and on Saturday morning. I noticed that I was bleeding Sunday. It wasn't brown, it was a red, like when I have my period. Then, yesterday October 10, I started having to urinate constantly and then it started to burn and then this morning I noticed that I am bleeding too. I have had UTI's and kidney stones before, but I have never experienced such pain while urinating or bleeding. Is this normal for a UTI?
