Thank you for posting your question here, I will try to answer it to the best of my abilities.
I recommend you use ulipristal acetate, it is a emergency pill that works up to 72 hours intercourse. As far as I know there is no dangerous side effect of taking an emergency pill, the common side effects are nausea
and change in your cycle, so that the next period is either earlier or later than usual.
I hope this answered your question.
