K I've had my period for over 6 years now. I just started taking birth control. Recently Ive had a brown/black subtance come from my virgina. I thought It was my period but blood isnt brown inless its been expose to the hair for a few minutes. I wiped my virgina and still brown so I knew from that point if it was period I would have blood on the wipe. Then I took a shower to wash it out to make sure i knew it wasnt period or else it wudnt have gone away that easily. I'm thinking it maybe the pills but i'm still worried I have talked to my doctor and they don't really know... I'm going for a physcial soon, but if you guys have any information please let me know, and please don't leave rude comments. Thank you.
