Period every other week !!! Came off Depo over 12 months ago

I came off the depo shot in August 19 after being on it for nearly three years. I didn’t get my period back until January 2020 and for the first few months it was irregular but normal, and then for the last 6

Months I’ve had a full heavy period every other month. I’ve had issues with anaemia in the past and I’m really worried, it’s making me Exhausted and I don’t know if this is normal!!

Has anyone else experienced this?? I’m thinking I might go to the doctors and go on the pill .. please help 😩
