hi as nordette ecp has a range of 120 hours i think you should be on the safe side of not being pregnant. so in the next two days you should start a period and this will be from when your periods will now start this is what it does. ok good luck
had unprotected sex feb. 8 and i took nordette pills as ecp on feb. 11. will it still work? my most fertile day was feb. 10. by the way i have a regular cycle.
