My girlfriend and I had unprotected sex on 5th April 15. Her period date was 7th April. But she never has them on time and are generally a week late. She took Ipill just an hour after the sex on 5th. She is also taking glycomet to regularize her periods. She has not got any bleeding till now. We both are worried. Is there any case where the ipill would not work or something like that? Please help anyone, we both are very scared.
