Irregular bleeding?

Kayla
So I'veade a post before. I've had two periods in the last month which isn't normal jul 30-Aug 3 and Aug 13-17.. the second one wasn't like a normal period.though it would go from a full blown period to spotting. . I went to the doctor on Tuesday and had blood drawn along with a pelvic exam and an internal ultrasound, they also took my urine. They wanted to check for cysts on my ovaries but didn't see or feel anything unusual.. well today the first 3 times I peed I need about 90% blood and 10% pee I'm not aure what to think they first time it was bright red and the other 3 it was like a dark/ light brown.. I haven't seen it since the middle of the day so I'm not sure what to think about this.. I have another appointment in the morning so they can collect a urine sample but I just want to know if this has happened to anyone else and what ended up being wrong?
