What does this mean ?

boymomforever 💙💙🤰 • Mother of five angel babies, a happy and healthy 4yo boy & a 1.5yo boy & last baby and BOY #3 due June 20 ‘23 💙

I’ve never seen this light of a test, ever. How could I have gotten this (top) yesterday and this (bottom) today ???

Did I ovulate ? Or what is going on
