I took my second shot of depo provera and I've been having unusual discharge since then. Sometimes it is a brown color when I wipe, sometimes I see small round balls a little bigger than a pimple head when I wipe or in the toilet, and sometimes both with a light brown stream flowing down the toilet. But I also have what looks like small tissue-looking tan in color chunks when I wipe or in the toilet when I urinate. The most irritating is the blackish streaks and chunks of mucous/tissue-looking chunks. Also, all of these discharges have occurred during and after sex. Is this normal and what can I do about it?
