When will I ovulate?

saralee

I started my period oct 18th ana ended the 22nd. My left ovary has been giving me pain since yesterday. I read online sometimes when you get pain it’s because the egg is getting ready to be released...? I Took an ovulation year yesterday and today & nothing. I’m so anxious. And don’t want to miss it. Once you get a positive ovulation test does that mean you’re ovulating at that moment or you will be?
