Is there still hope for me...13dpo w/ bfn

Bre • 28 TTC for #2 with my best friend and love of my life.
Cycle day 26 of a usual 23-24 day cycle, still haven't gotten AF and all my test are BFN. Glow had me at getting her today but no sign of her yet. Is it possible to be prego even though I'm getting a BFN at 13 dats DPO. No signs of cramps. My temps are ok I guess. I ovulated on the 27 (I think) thoughts!??
