Don't know what to think .....

I added pictures of my calendar and I'm confused. In March AF came right at day 29 which is spot on. Glow said I started ovulating right after AF? That doesn't sound right. Then my next AF came early was very light and a day short. Last AF was due May 9th and still nothing. Hpt still negative. Blood test on May 16th negative. Any advice. Not sure what to do.
