I had unprotected sex on 29th of July and had I-pill within 12hrs. My boyfriend didn't ejaculate in me still to be on a safer side i took the pill. I read an article saying that the side effects to the pill starts within 7 days of taking the pill. It's been 9 days since I took the pill and I haven't have had any of those side effects. Is that normal? Is it normal not to have any side effects? My period is supposed to come on 21st of Aug and it's 8th Aug today. Is not having the side effects normal? Is the pill doing its job?
