Hi thanks for contacting health care magic Noted you have foul smell vaginal discharge.... So here cause has to be searched ... Mostly it seems to be vaginal infection condition. For that get your per speculum examination.... If thick white discharge seen then it could be fungal candida infection. Clotrimazole local application useful for it. If thin , malodourous discharge and not white colour trichomoniasis or bacterial vaginosis can be there..... So for that better to take vaginal swab and according to causative organism drug given. Maintain hygiene.... Clean genitals after sex.... Drink note water. With keeping this in mind consult gynecologist for examination and accordingly investigation... Take care.
