I had sex on 4th october. I was not on birthcontrol pill. We used condom. I am not sure if the condom broke down or leaked. And within 5 hours i have taken the emergency contraceptive pill. I got my period on 10th october(5 days late) but it was very lightly just like spotting. Was it actually a period or just the side effects of contraceptive pill or are there any chances of pregnancy?
