Did I ovulate?

Ca

Hi! Prior to today, the fertility friend app said I ovulated on January 22. I should be 18 DPO today. But this morning when I entered my BBT, it took away all of my crosshairs/luteal line. I did ovulate correct? My temps are still high at 18 DPO, but my pregnancy tests are all negative. I am SO confused!!! 😭😭😭
