Period every two weeks

Hi! I have been dealing with this for 1.5+ years. Ive been to the doctor been on bc, switched brands and it never helped. I finally stopped taking it last month because i had side effects and was still getting my period and was fed up. I was going to go to a new doctor but if the are going to just put me on a pill which i don't want, patch no, shot no, and i'm only 19 and don't want an iud. Are their any other options??
