I need some help ..

I had unprotected sex with my fiance and he pulled out before cumming , i took emergency pill 2 hrs after we had sex . It happened on 18th of jan . My last menstrual date was 5th jan . After taking the pill i bled , it happened on 24th of jan and i bled for 4 to 5 days .

I just want to know if i am going to get my regular periods on my date that is 6th or 7th feb or not . If not , should i take a pregnancy test or its normal ? Plz I have my exams and I am not in a position to stress over it as my periods don't feel like coming ... Please help me sweeties ❤
