We have unprotected sex last June 7, 2014.. I took Nordette as an ECP.. I took 4pills (20hrs after the unprotected sex) and another 4pills after 12 hours. But we have unprotected sex again last June 18, 2014, 3 days before my expected period. My boyfriend assured to me that he did not ejaculate inside of me. I did not took any ECP since Im expecting my period 3days after the do. My expected period was last June 21, 2014.. I am 1day delayed now. but I can feel the symptoms of menstruation, but as I read some article, it can be signs of pregnancy.. Im so paranoid. Am I pregnant? Does the ECP will take effect eventhough we had unprotected sex 3 days before my expected period?
