If the PT is negative it's very likely that your not pregnant. For the bloating I didn't have a period for a whole year but i still had mild pms at the time I would have a period everyone is different tho. And if your having an odd smelling discharge coming out of your vagina I would go to the doctor just to make sure you don't have some type of infection because that can be a sign especially if it's yellow or green in color. Good luck.
