Help with ovulation timing

I’m still learning how everything works so forgive me. I had my first positive ovulation test on the 28th and a very positive one on the 29th so I thought I ovulated on the 29th. Glow changed the date to today so I’m a little confused. Should I have ovulated yesterday or today? My husband and I aren’t really trying (even though it doesn’t look like it lol) we’re just not preventing. We agreed we’d start actually trying when our daughter turns one in June so I’ve been tracking my cycles just to figure it out.
