Hello Shakeel, Thank you for proposing your query. I would like to stress upon the fact that most vaginal discharges are completely normal, however, if your vaginal discharge has an unusual odor or appearance, or if it is accompanied by itching or pain, it may be a sign of a underlying infection. My suggestion to you is to get yourself examined by a competent Gynecologist if you have above mentioned symptoms along with white vaginal discharge to rule out a bacterial or fungal infection. Once confirmed, you might require medications to combat the infection otherwise, don t. Since you mentioned that you get your periods only on taking susten, I would like to know your age and also since how long you have this problem, only then I would be able to give you my opinion. Hope this answers you query. Good Luck. Take Care.
