Help!

I went to the doctors yesterday and had to do a urine sample. I was tested for pregnancy which was negative. But then I had a different test, and there was blood found in it so it's being sent away for testing. Also I have had the frequent need to pee almost every hour and bad pain in my pelvic area. I don't want to wait for the results to come back as I am anxious about this and just want to know what it is now. Has anyone had anything like this before or may know what it is?
