okay so here is the case..on 3rd of may we had sex and we used a condom and she took an unwanted 72 two hours after the pill..after that she recieved her periods on 7th which is 24 days after her last periods.. And then again we had sex on 23rd of may and this time she did not took any ECP but we used condoms very precautiously.. And now its 35 days from her last periods she did have one.. she have no signs of pregnancy like tender brests,fatigue,mood swings etc.. is it the last unwanted 72 she took which is causing her to miss her period? Can it be possible? please help i am very very scared i am mere 19..
