Concerned and In need of advice!

Alright, ladies. I'm sure a few of you have been here before. So Friday night/Saturday morning, my ex fiance and i got drunk, and had sex, unprotected & pullout method, twice. My period is due either Sunday or Monday (can't remember). My symptoms are different than normal today. I'm worried that because we were drunk, maybe he didn't pull out in time. I can't remember. It was very unsmart, and also unplanned, so please no hate for that. I guess I just need reassurance. Also confused, would I still get my period if I conceived the day or so beforehand? Thanks guys.

Also I'm 21, so I'm not unintelligent, we just maybe made a bad choice. Again, please no hate. I'm sure some of you have been here. Thanks ladies
