I have brown flakes in my urine. looks like dried up blood maybe. last period was over a month ago. what's going on?

Several things: Problems like these can only be correctly handled by your doctor in person. A urinalysis will help identify the culprit.

Possibilities: Spotting prior to period can occasionally occur prior to the onset of bleeding and not be a cause for worry, but there are other causes of irregular bleeding: pregnancy, fibroids, endometriosis, stds, infection, a cervical or uterine polyp. Other causes could be a bladder infection or kidney stones. Irregular vaginal bleeding or blood in your urine are both absee your doctor to find out for sure.
