17 DPO, AF due in 2 days, elevated temp, but BFN

Al

So I feel like this is wrong to begin with because I ovulated early (cycle day 11) but glow still estimates my period to be due in 2 days at 19 DPO. My other app says I'm 4 days late but I'm still getting BFN. My bbt has also been in the 99s since 11 DPO (6 days ago) but theres no way im pregnant if I'm 17 DPO and still getting negatives right?
