Hi Good Morning, I Had Sex With My Fiance Yesterday

Hi good morning, I had sex with my fiance yesterday morning but with a condom, but she is scared as we don't want a baby before wedlock, and she took postinor2 tablets (2 of them within 5minutes interval), in the evening of same yesterday. And this morning, we had sex (unprotected) again but I didn't cum inside of her. Now we are worried and scared. Do you think we should not?
Thank you
