Thanks for consulting. I have carefully worked through your case, and I can realize your health worries. Being your physician, I assure you not to worry as I will take care all of your medical concerns. yassmin is an oral contraceptive pill. it is not effective for such situation. i will suggest Ipill or other emergency contraceptive pill to be taken before 72 hours. always use condom when you are having intercourse to protect from pregnancy and sexually transmitted diseases. Hope it helps. If you need further, detailed and quick assistance related to any health issues in future, feel free to ask me a question directly from my profile. Have a wonderful time ahead. Best Regards! Dr. Arunmozhi varman
