Hi, i had unprotected sex on 29th dec. Though my boyfriend did not ejaculate inside me I took an ipill within 24 hrs for safety. I am having vaginal bleeding after 4 days of taking the ipill. The bleeding is light but has been happening continuously for 3 days. I am worried. Is this normal? I am expecting my periods on the 22nd Jan. for how many days does this irregular bleeding/spotting happen? does it mean im pregnant?
