Hi, Welcome to Health Care Magic, thanks for posting your query. I understand your concern. Unwanted 72 is an emergency contraceptive pill, and it should not be taken as a regular contraceptive pill. It is meant for emergency situations when you have unplanned unprotected sex. I strongly suggest you to stop taking the pill as regular as you are taking it now, because it sure does have side effects and a could cause permanent changes to your menstrual cycle too. It does have a effect on your chances of getting pregnant in the future. I advise you to meet a gynaecologist at the earliest who will prescribe you a regular contraceptive pill which you can take daily to prevent pregnancy, also you could ask your partner to use condoms to avoid taking pills. Hope this helps, and answers your query satisfactorily. Do write back to me if you need further assistance, Wish you good health, Take care. Regards.
