Well I will tell you like this almost every female goes through that like the other women said if it is about a week before your period then it is your body getting ready for your period you might even just notice a slight clearish white discharge as well before your period but that is normal your body is just preparing itself its just one of those side effects woman have to suffer unforuntantally. Now if your period comes to an end & your still having problems than go to the doctors. If your not sexually active it can just be an VD that is caused naturally from your own bodys PH system it happens almost all the time can be as simple as you eating to much sugars changing soaps. So just pay attentiion to it.
