I've had unprotected sex with my bf last December 22 morning, it was the last day of my period. I took nordette as an ecp with the first dose after 11 hours of the deed and another four after 12 hours. I experienced bleeding after 4 days that lasted for about 4 days. Up to now, i still haven't got my period and I'm a little worried. But I've already been experiencing pms symptoms but as we all know it's the same with pregnancy symptoms. Please help me. Is it possible that I'm pregnant or is it the ecp working?
