Too late for hopes up?

So im currently 13dpo, neg tests so far since 8dpo with fmu.

Usually that would be enough to count myself out HOWEVER, i have had enough periods to know i get crazy PMS, diarreah and leg cramps before AF.. AF is due tomorrow and i feel none of it. bbt is high at 37.1c, and my cervix is higher than it was last week.

I know you arent out till AF shows, but this month i just feel "different"

Is there still a chance for me or am I driving myself crazy and looking for signs?
