Hi, I had unprotective sex with my gf on 24th Nov, The chances of pregnancy are narrow as i pulled off before ejaculation, but still since she missed her dates there is doubt. Her periods occurs during 26-28th, it seems it missed this time as 28th has passed. Today is the 5th dayafter sex, Is there any pill we can take now to prevent pregnancy. Please suggest some pill which can be taken within a week or 5 days.
