Need Opinions -CD 45!!

Mel
So today is cycle day 45.. I ovulated on cycle day 33 I am now 12 DPO. I tested on 9DPO and got a BFN.. My Boobs are SUPER SORE and tender. I usually get like that when I'm starting my period, but it's been almost 2 weeks now and still No AF. Should I take another test or save myself the heart break? I really don't know what's going on with my period now.. Any one else having this problem?
