My last menstruation was oct 20+ (probably oct 23-27).my bf wasnt able to withdraw during our unprotected sex last nov. 14 and morning of nov. 15. Its only on the night 10pm of nov 15 that I took 4pills of nordette as an ECP then 4pills 10am of nov 16. I continued taking the rest of the pack and finished them last nov 28. And stopped. Sometimes I feel nauseated but I am almost delayed by 2weeks by now. It is only last nov 24 that I have this very pale red blood discharge and it was never repeated. I am still sexually active but my bf is withdrawing it ever since nov 14. should I be worried now? Did I do the right procedure?
