the egg should not be in uterus anymore after menses, am i right? the day after period ended to roughly day 13-15 is non-fertile period (well to make it safe day 10 its just a rough estimate). if sexual intercourse happen in the period the pills are not needed unless the couple wants to ohm ohm all the time. It is only required after she ovulated (2 weeks after menses) and till before her menses come.

i take the day after the menses as day 1, my knowledge about it has gone down the drain already. thanks for correcting me
