I’m starting to think I didn’t ovulate

mydream

My chart doesn’t show if I ovulated or not and I know my temps are all over the place but I tested positive at 9dpo on 6 hpt (different brands) and got positives on them all. Tested 10-21 dpo EVERYDAY and is getting nothing but BFN! Now my period is 7 days late and I can’t figure out why! I’m NEVER LATE
