Need help with OPK

I have been taking OPKs continuously to figure out my body because this is our first month TTC. From what I understand I ovulated on the 23rd. (I have pictured below with the date on the side) but I kept testing really just for the hell of it. Now it’s the 28th and I tested again (separate picture below) and I think I got another positive? Did I not ovulate before and I’m ovulating now? Is mine today positive? HELP! Thanks in advance!
