Probably and UTI. I had the same exact thing. They don't do anything bad, they only give you antibiotics. It's an always wanting to urinate feeling and it burns sometimes and gives a weird color.

Embarassing story about mine....
I was in school and went to the bathroom 17 times from a school time of 7:45am-2:21pm and I went to the nurse since my mom told me to so maybe I would be sent home from school. The school nurse asks me if I'm sexually active and I said "yes". She then calls my mom at work with about 7 other kids around me saying "I believe your daughter Jessica has a urinary tract infection". I didn't know the kids were there till I turned around. So now those kids know I have sex and I have a UTI. Haha.
