For the past week I have been experiencing extremely heavy, dark brown discharge. I have had a problem with spotting between my periods for years, but this is unlike anything I have experienced. I use about one average sized pad per day which, for me, is much less than my regular period, and much more than my regular discharge. This discharge has been accompanied by mild nausea and slight abdominal and back pain. I recently stopped taking the birth control pill a few weeks ago, and I was wondering if these symptoms could be due to my discontinuance of the pill, or if in fact I could be pregnant (these symptoms started the day after the last time I had intercourse). And if neither of those sound plausible, what could be my problem because it seems to just be getting worse. Thank you for your time.
