I had a period two weeks late and it was very light, brown spotting. Then I had a period two weeks later that was a normal heavy flowing, cramping, bloating period. After the second period was done I had sexual intercourse with a man, and I bled a little I didn't think anything of it (we have used protection every time) I took pregnancy test a week ago and it said I was negative.. this morning I woke up with huge abdominal pains that happen when I urinate and blood is appearing when I pee. When I went to wipe there was a pretty good size blood clot. Do I have a UTI? Am I pregnant? Do I have cancer? What do I do?

Unfortunately we cannot diagnose this via the internet. You will have to see your doctor.
