Birth control decisions PLEASE HELP

I am 20 years old and have been on the pill since I was 14. I am looking for a new birth control method because being a college student makes my schedule impossible and makes me even more forgetful due to lack of sleep. I have heard that an IUD is a painful process to put in. But I need to be on something because of my extreme periods, and my partner and I are sexually active. PLEASE HELP and give your preferred birth control methods please 😊
