Is there still a chance of getting pregnant if I had unprotected sex and took the i-pill (Unwanted 72) today?
Yes, there is still a very small chance of pregnancy, as no emergency contraceptive is 100% effective. However, because you took the i-pill (Unwanted 72), which contains levonorgestrel, on the same day as the unprotected sex, its effectiveness is very high. It works primarily by preventing or delaying ovulation. For your peace of mind, I suggest taking a home pregnancy test if your next period is delayed by more than a week, or in about three weeks.
