New to ovulation tests! Please help!

Emily • Wife, mom, and ttc baby #2.

So I know the test line has to be as dark as or darker than the control line. If it is does that mean you’re ovulation? Or you will sometime in the next 24 hours? Also when it the test line reaches that point is it best to try to get to get pregnant that night or the next night? (Sorry if that was worded weird or if these are super basic stupid questions)
