Dear Doctor, My girlfriend is 25 years old. We have been dating for the past 3 years now and are committed. She explained to me that from the time she first got her periods, they have been rather irregular. She would also develop certain skin conditions during her periods such as acne on her face or increase in oiliness as well as dryness of her lips. Her gynac after performing certain tests said that she releases several eggs at a time, rather than the usual one when she ovulates. Under his prescription she has been taking a course of Aristelle (Ethinyl Estradiol, Dienogest) ever since As I understand, this drug is a hormonal contraceptive. She has continued this course for the past several years now and has been doing well in terms of skin symptoms and regularity of her period. My question to you is, for how long do you think it would be safe to continue this course without causing any disturbance to her body. We are clear that we want to have sex only after marriage. Hence I would like to know if there would be anything to keep in mind when we do decide that we would like to conceive. I look forward to your kind help. With Gratitude
