Hi, me and my girlfriend had unprotected sex, on december 1st, i didn t ejaculated inside of her but for precaution she immediately took nordette ecp, 4 pills 1st dosage and after 12hrs 4 pills again, it s been 11 days already and she isn t showing signs of bleeding(spotting) or anything, her last period was on november 11, should we take a pregnancy test or wait another week to do so?
