is not an emergency contraceptive
and as such, if ovulation had already occurred prior to its use, conception can occur. It is a regular oral contraceptive. If she has regular 28-32 day cycles, you had intercourse during the fertile period, and so, the chances of conception are higher. I advice you to get a pregnancy
test and follow it up with a trans-vaginal sonogram, if positive and get further help from your doctor. Take care.
