hi, I'm a 36 year old female. For the past 3 days I've been experiencing some vaginal discharge and itching but no burning. What concerns me is that at first the discharge was very dark looking almost like black,and then it turned brown and smelled bloody. And now it's completeley white but not liquid olmost like dead sperm..pieces of tissues..please if someone can just give me an idea of what it may be.I had a baby about an year and 7 months ago and every since i experience that dark slimy liquid...i thank you so much for your time..
