I dont think you need to worry about getting pregnant. It is extremely unlikely that you have conceived. It is common for periods to get post poned or preponed by 7 days. Even if you did have unprotected sexual intercourse, there is no way you could have conceived. iPill
can delay your period further. Avoid taking it the next time.
Dont worry. You would get your period in a week to 10 days.
