I had unprotected sex with my girlfriend 5 days before her normal date for period. That is normal date of period was 30th June and we had sex on 26th June Afternoon. However, she took an i-Pill within 4 hours, after having some meal. Its been around 1 week from the normal date and she has not received her periods yet. Day before yesterday she was feeling some pain just like the one which she experiences before every period. But she took a painkiller. I hope that should not affect the periods by delaying further. Please help and tell me whether she is in safe zone or not.
