A couple days ago (4-8-09) I noticed a little pink on my underwear and on me when i went to the restroom. Couple days went by and i wasn't to worried about it, but when i got up this morning (4-11) and got to work, I went the bathroom and there was a lot more heavier blood then before. The color was a darker red, almost brown, and sort of thick. I just got off my period maybe 2 1/2 weeks ago, if that. My periods have been normal and on time since I first started. Cramps are bad and random throughout the day. I don't know what to do. Any advice would be much appreciated. Thank you!
