Is this a chemical pregnancy, just late or body messed up????

I have very sensitive sore boobs and have been like this for at least a week all over and even in my armpits.. & this NEVER happens not even before my period. Ovulated 10 April BD days before and day after. But BFN for all this week & im was due on yesterday! 

This makes me 11 dpo today since positive opk. Periods are normal since stopping pill in December 27 day cycle. 

Anyone have similar experience & still got BFN or BFP? 🙏🏻 thoughts please!!!!
