Hello. I Had The Jadelle Implant Inserted 5 Months Ago

Hello. I had the jadelle implant inserted 5 months ago and it has been a nightmare of never ending periods, weight loss, terrible emotions and thinning hair. I have taken norethisterone for the bleeding but every time I get off it, the bleeding gets worse. My questions are, how long is this bleeding for? Does it get better or must I remove the implants? Also could you recommend something else for the bleeding?
