You may have a yeast infection. Some woman are more prone during menstruation due to hormone changes. However with you also douching, this can cause the pH balance in the vagina to change and have the bad bacteria to take over. Douching is not recommended unless 100% needed and should only be done on a rare occurrence. So do stop doing that. If there is no change in the next few days, I would follow up with your doctor. In the mean time do start eating yogurt, and even do this prior to and after you cycle. If you normally wear pads, if you are able to, try tampons or try a different pad.
