I have a period cycle of 28 days. My last period was on 29th jan and I had unprotected intercourse on 13th feb but took ipill within 30 mins. It was the 15th day of my cycle. My next period is due 25th feb. Today is 20 feb there is no sign of withdrawal bleeding it?s been 7 days since I took I pill. Last time I got bleeding within 5 days. I?m really worried. Am I pregnant? Please help!
