Cycle help

Amy • Wife 💍 and mother of 3 boys 🦖🦖🦖

My entire life I have always had a 28 day cycle with or without birth control. Since I had a miscarriage at 15 weeks in April I’ve been on 2 different birth control pills and I’ve been late every single month. Do you think if I go off birth control I’ll go back to having normal 28 day cycles? Or what can I do?
