CD 33 no period BFN help! TTC

I have had 28-29 day cycles for years. Last time I had a cycle that was more than 30 days was when I was a teenager. I did the BD prior to and until the week after ovulation. So even if I OV late I was hoping to be ok. I started having what I thought was PMS symptoms a week before my period was due but now it’s been close to 2 weeks I’m still cramping and having back aches and leg aches but still no period. I have taken tests and still BFN. I have yet to take a FRER which I will try in two more days if AF doesn’t show. This puts me at 17dpo today on CD 33. Is there still hope? This tests is a FR rapid result not an early result. I think I see something but it could be an evap. I need opinions TTC baby #1.
