Honest opinions please

I am 16dpo confirm with bbt on fertility friend. Sometimes my bbt can be a bit wobbly but I am certain I O'd 16 days ago. I also track my resting heart rate on Fitbit and that matches with ovulation 16 days ago.

On 14dpo (day my period was due) I had bright watery blood (tmi sorry) first thing in the morning and was sure it was my period as matched up with all other pre-AF symptoms (crying, cramping, spotty face).

I've had NO bleeding since then not even a dot throughout the day.

My RHR on Fitbit has come down.

My bbt went from 36.5c to 36.25 yesterday and back up to 36.38 this morning.

BFN 15dpo.

Should I just expect my period and be patient? Would you hold out hope? I know you're 'not out until AF' but I just need some realistic expectations so I can concentrate on normal life.
