Clearblue OPK question

Hi Ladies,

I tested yesterday morning and got a positive result. Then tested around same time this morning and got an empty circle.. If I got a positive yesterday can I assume in the next few days I'm ovulating? and today I probably just missed my surge? Do you test again the day after a ppsotive result? I'm confused, havent used these in a year. Thanks ladies. I don't know what I'd do without you all.
