hello doc, 

I wanted to know that how much of a delay can I-pill cause? 

I had unprotected sex in the heat of the mo moment  7 days after my cycle and we both weren't sure if he came in me so I had an I-pill immediately the next day. After 11 days of having it I had bleeding for 3 days it wasn't like usual periods and when I read about it they said it could be discharge due to the medicine. This was 7 days before I expected my periods. 

It's a day delay now. What should I do ? 

Seeking for best advice.
