Wanting to give up on glow

Seems I'm posting yet again only to be disappointed with no one having any opinions but hundred read my struggle.... 
My husband and I r TTC baby #1 
I'm a 24-27 day cycle usually I'm currently on CD39 glow keeps pushing my period date back... I had a positive ovulation test on CD 17 also CD23 I was late and took a pregnancy test on CD 30 and BFN 😔
I'm now on CD39 and have had positive ovulation tests for 4 days straight.... What's going on?? When will AF come? Could I still be pregnant??
