But realistically speaking just for some sound of mind, she shouldn't get pregnant right?
Doesn't sound very likely to me. You won't be able to test accurately until around the time her next period should be, but her period may even come early because of the pills. Good luck with everything.
She took the emergency contraception - changes are highly unlikely.
Probably a low possibility but she should test in about 3wks to be sure.
Chances are low. If you didnt fully ejaculate & she took a plan b pill then she shouldnt get pregnant with the extra caution she had.
