So I have been feeling nauseous for the past two days (diarehhea and sweating.) So I go to the washroom today and I see this brown stuff in my underwear (I thought it was skid marks from having diarrehea) so then I look but it was comming out of my vagina! I went to the store to get pads and I have worn them but nothing is really showing up on them. I also have some stomach pain but I'm really confused please help!!!
