Frustrated! Am I ever going to conceive.!

6-7+ months trying to conceive. I thought this was our month. Mild on and off cramping from 6/7 dpo to today 14 dpo. Sore boobs. Temps still above coverline however I took a test this afternoon (last day of expected period) and BFN. I thought we did everything right this cycle. I guess I should be expecting AF within the next day or so. Paying me a visit late. So bummed!!
