Nexoplan implant bleeding

Okay so I got the implant in my arm around late August, I began bleeding two weeks later. I’ve heard that bleeding for prolonged periods was normal for like two months or so after you get it but it’s supposed to stop. It’s now middle/end of February and I’m STILL bleeding continuously. Not just spotting like for the most part actual bleeding. I think the longest its stopped in these past 5 months is like 5 or 6 days. I don’t think it’s normal to be bleeding for over 5 months but idk? I’m not sure if I should just continue waiting it out or make an appointment and talk to a doctor?
