For 2-3 years I have had a cottage cheese like discharge coming from down stairs. It s associated with a very nasty unbearable odor that has only become more consistent and recently my periods have become more painful than normal. Also they are very black and clotted looking. I didnt think anything of it til my boyfriend told me my vagina was stinky. Is this a normal thing or do I need to go see a doctor. I also should point out that 2 years ago I hadd a miscarriage. I wasnt very far along and didnt go to the doctor for it and breast cancer runs in my family. (Mom grandma and both aunts )
