I am 28 years old unmarried female and had unprotected sex with my partner 20 days back and after that I had taken emergency contraceptive pill named I pill. According to my menstrual cycle I am accepted to start my periods but they didn't start yet in tension of getting pregnant I had taken one more I pill yesterday. So my question is what will be the side effects of having emergency contraceptive pills twice a month is there any complications will occur in my current situation or in my future pregnancy? And due to this I had missed my periods? And when will my periods will start. Is I am not get pregnant? What should I do please suggest as soon as possible. I don't want DNC which causes marks on uterus is there any other method of abortion without any side effects and never any body now about this in future.
