Why Am I Urinating More Frequently And Having Back Pains Why Do I Suddenly Have The Urge To Urinate Frequently In A Day?

Why do I suddenly have the urge to urinate frequently in a day? - why am i urinating more frequently and having back pains

This problem started after she had sex with my new friend for the first time after a few days I go to the toilet more than ever, and do not expect the pain when I urinate. Also I am when I urinate bleeding. I thought I had my period.

What is wrong with me? I call my doctor Monday, but I need to know now. Anyone?
