Hello,
I had unprotected sex with my fiancee on 4th Jan around 1.30am and she took an emegency contraceptive immediately we were done and had the second dosage at about 7.00pm that evening. By my calculations it must be either 1st or 2nd day after her ovulation(all things been equal). Her last Menstrual period ended on the 22nd December.2014. And even till now she hasn't seen her menses.
Could it be that the EC didn't work? Or the alteration has been caused because we had administered a single pill(not the two pill) on the 25th of Dec when we were not sure if the condom broke or not.
