Once you stop taking the pill, the hormones are out of your body quickly, usually within a couple of days. When the hormones are gone your body needs to start again on its own to function. That mean it will start producing follicles again, which eventually lead you to ovulate. Everybody acts differently, some may take a couple of weeks to ovulate, other may take some months, but in general your body should be in "normal mode" within less than two to three months after stopping the pill. So if you now ovulate normally, that means your body is back to its normal rhythm.
