Hello! So I Was Told To Start Using The Birth

Hello! So I was told to start using the birth control that goes into your arm. The one that's the size of a tooth pick and is inserted, I can't remember the name. But I got it after a misscarriage about a year and a half ago now, and over that year and a half I've had my period go from 3 days to currently being 2 months long. Consistent bleeding all day. Should I get it removed? My mom has a protein s deficiency thats hereditary and she was just diagnosed with lupus
