Anyone have late AF & BFNs then get a BFP?

AF is usually right on time but I'm a day late this month. I don't have any of my normal pre-PMS symptoms but I'm having some different symptoms that could be early pregnancy, like super sensitive (almost painful!) nipples & boobs and I've been gassy (eww!) the past week. This is really out of my norm.

My question is, have any of you gotten a BFP after negatives during your missed period? I have a friend who said she got hers a week after her missed period. Her cycles were irregular though and she wasn't really tracking ovulation.

I'm so confused!!! Just looking for others who experienced this and trying to keep some hope that I'm not out this month.
