Ovulation

A

Hello everyone

How are you today?

I'm first time mom and I am on BC. I'm thinking of stopping BC, but I noticed that my ovulation while I'm taking BC is near my period by a day or two(I even used CB ovulation tests to make sure) when I stop BC will my ovulation still be before my period by 4 days or less? Or is it because I'm taking BC the ovulation is mixed-up?
