Anyone expecting AF today??

y

So today AF is supposed to arrive. I haven't had much signs she's coming. I got brown discharge starting Monday but it's been light and yesterday almost non existent. No cramps or anything.

I tested today and BFN. I didn't track anything this month, just kinda went for it and thought there's no way I hit my ovulation day.

I had some sore boobs the other day which I've never had before AF.

Has this happened to anyone and gotten a BFP days after AF was supposed to show??
