Hi Madame, Then it could be BV (bacterial vaginosis) Just get down to your local STD clinic and get some tests and they should sort you out.
Good Luck
If your a man could be gonoreah or climidia but you would also have some burning and itching in the ureritha. If a women a yeast infection. Have it checked out asap. 7 days is the incubation period for the men things.
