So i have this acne problem and my dermatoogist advised me to start on yasminelle. After taking the 21 pills im on the break period... now today is the third day without the pill and still have no period. Durinf the 21 days i did have some bleeding but now i am waitkng and still have no period ... should i start the second box of yasminelle if my period comes on the 7th day? And what if i dont get a period? I am not pregnant for sure as i did not have any sex...
