19 DPO, negative HPT, and still no AF?!?!

Sakinah
I've been testing on and off for the last week.  Each time getting a negative. I don't understand what's going on with my body!
​I went to then doctors at 14DPO and they said that based on my glow info I  gave them that I could have to wait until the 7th to get a possible +... I don't get that. I got a positive 4 days BEFORE my AF about 3 months ago. Sadly that ended in a MC
​Ok I'm really trying to stay positive!! Did anyone else get their BFP at a late DPO??! Anyone?? ? 
​Also I have sore bbs, cramping a few days ago, and I wanna eat everything in sight. Is there still a chance???
