Helppp ‼️

One year ago I started taking the birth control pill and I’ve gained over 20 pounds i barley ever eat and I’m always working out so I know it had to be the birth control, then I got a job where they were working me WAY to much 91 hours a week is way to much for a part time job ! So I’m the mix of school and work I just kept forgetting to take my medicine so I just stopped and it been about two months , and I want to start back with birth control because my periods are so heavy , but I’m not sure I thought about getting the bar in my arm , or the shoots but I’m also trying to lose weight so I’m not sure what to do , any suggestions?
