Hello dear I understand your concern Postinor 2 contain high progesterone. You have used Postinor so frequently in one year and also undergone medical abortion. It cause hormonal imbalance, ovarian hyper stimulation, menstrual irregularity infertility issue in future. So I would suggest to avoid excessive use of the postinor 2. Use it only for the emergency purpose. Use barrier contraception like condom and diaphragm regularly to prevent the pregnancy. If you did sex in fertile phase of the cycle then only take postinor 2 last time. But in future avoid postinor use Avoid stress, take healthy diet, drink plenty of water and do regular exercise Hope this may help you Contact HCM for further health query Best regards Dr. Sagar
