What do you mean by the 4th day of ovulation? Four days before the day of or 4 days after?
Postinor 2 prevents pregnancy in two ways. First, it prevents ovulation. Second, if ovulation has occurred, it causes changes in the cervical mucus to make it harder for sperm to reach the released egg and cause fertilization.
Once you have vaginal bleeding, you will know the pill worked.
