Sir me and my girlfriend both are 24 years old. We had unprotected sex on 13 june and she has taken I pill just after sex. And after 10 days on 23rd june she had bleeding for 4 to 5 days. Which I guess known as withdrawal bleeding. And from 23rd june today se 23 july period has not come yet. From 23 june to 23 july one month completed and today is her period date but period has not come yet. And we were also sexually active on 14 july and 20 july. What to do. Does I pill cause this delay or what? Please tell me what to do. We both are very worried.
