Me and my girlfriend both are 24 years old. We had unprotected sex on 13 june and just after sex she has taken I pill. And after 10 days she had bleeding which I guess is a withdrawal bleeding. Withdrawal bleeding date: 23 june we have sex on 14 and 20 july also. And today is 23rd july one month from the withdrawal bleeding date. But period has not come yet. What to do. Does taking I pill for the first time delay period?
