How long after stopping birth control were your periods back to normal?

Mary • I`m Mary Edmonds, I`m about to be a nurse, I love my cats, Netflix and would die if I had to do something I hated.
Before BC, my cycle was exactly 28 every time with 5 days of bleeding. Now, it can range anywhere from 29-40 days and that always stresses me out, which delays my period more. How long did it take your period to snap back to normal? I've been off birth control for a while now. I believe more than six months? I can't remember the month I stopped.  I was on it for a year. It's was Microgestin FE 1/20 if that helps?
