This also has happened to me and it is yeast infection and you can cure this by taking medication or if you don't want to go see a doctor then you can eat a tub of plain unsweetened yogurt everyday and or put some on a tampon and insert into vagina or get a clove of garlic and tie a string and insert into the vagina or eat garlic by mixing it in with daily foods and drinking cranberry juice up to 7 times a day
Whitish discharges are typically due to yeast infections and they are very common. There are over-the-counter treatments can help get rid of it.
