3 days of pure un-surety!!!

So; for some time now I've not exactly been TTC ... BUT we never use protection and he always cums inside... So I think we both are aware of the possibilities..... && we have done it maybe every weekend for about 2 months now. Last week I took a MAP (morning after pill) and I also took one this Thursday. I herd that they could mess with your cycle flow. I'm kind of hoping that's sort of/not sort of the case here because I'm 3 days late && I'm NEVER LATE! My AF ALWAYS comes like clockwork. Every month. Since I was 17. I'm kind of starting to freak out because I've taken about two UPTs since the date of my missed AF and they both seem to be BFN!!!!!!! 😖😅 any ideas what could be going on here?????? Kind of frustrating to see all the BFP for Christmas miracles and I'm over here loosing my mind as to weather I am or not. *Btw; I've only this morning started to actually stress it. So I doubt it was stress from before why my AF is late.*
