Implanon/implant contraception! Help

7 weeks ago I got the implant/ implanon contraception rod in my arm, when I went for a termination.

I have not stopped bleeding for 7 weeks straight now,

Is this normal?

Does anyone know?

Help would be great , I'm really sick of having my period 24/7 it makes me feel very yuk and like I just dont want to do anything!
