Am I Out This Month??

Hi ladies! 
I am two days late. I took an OPK this cycle and got my peak fertility symbol and everything. Had sex every other day. 
I am having mild cramping and increased appetite just as if AF is on its way. 
However I'm having super sensitive nipples and achy boobs. 
Does this sound like AF or possible early pregnancy? Have any of you experienced AF symptoms and still got a BFP?
I'll be testing next week if AF doesn't show.
