postinor-2 would mess up mestruation cycle

Just to make sure here,i read every page and post...but doesnt really answer this question:

we had intercourse on 12pm and she took the pill 2-3hours after,
and we had intercourse again on 6pm and 10pm(yah i knw we r horny).
She took the 2nd pill on 12am...is it safe?

General question:Does the pill work if intercourse were to happen between the first and the second pill?

i know there are chances to get pregnant no matter what unless
we avoided intercourse =D

thanks alot!

EDIT: also she was the one who wanted to use pills...i treat her like a princess ok.

Get ur boy to wear a cap. that is one way or another is to use spermicide.
