Hi there! I am 21 years old and I am very embarrassed to ask this but I was wondering what could cause a brown liquid to come out of my vagina.. I am sorry I know this is a really gross question but I cannot afford a doctor at this moment and I need to know. I will also let you know that I do not have regular periods. I have not had a period in almost 6 months. I did go to the doctor almost a year ago to find out why I wasn't having periods and they couldn't find anything wrong. So why is this happening? Please, no immature responses. I am concerned. Thank you!
