Hi, Microgynon contains both ethinyl estradiol and levonorgesterol which is used in the treatment of heavy, painful or irregular periods. It is also used to prevent unwanted pregnancies from unprotected sexual intercourses. Each female reacts differently with regard to difficulty going on Microgynon as well as then coming off the pill. Some female might experience hugely bodily changes, while others experience a few changes or no changes at all. However, after stopping this medication abruptly, you may suffer from side effects such as irregular uterine periods, heavy and prolonged bleeding, spotting or breakthrough bleeding between periods, breast tenderness and enlargement, nipple discharge, vaginal discharge, vaginal dryness, changes in sexual drive etc. If these side effects persist for long or bother you, then you should inform your doctor first for medical help. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Zubayer Alam, General And Family Physician
