Birth control.

I want my period to be regular again. I got my first period when I was nine. When I turned 12 I got put on some regular birth control pill I forgot the name and it made my periods super regular then I turned 14 and was like screw this bleeding and tried seasonic cans had a period every three months. Then I became sexually active and couldn't miss any pills so to better prevent pregnancy I got the implant in my arm. After getting that I had no period for a year then I bled for a month straight and now my uterus has no schedule and it's messing with my life. I'm 17 now and I haven't had sex in a while and don't plan on it. But I want my period to be regular so I can plan. Does anyone have any recommendations or advise ?
