I Have The Nexplanon Implant And Have Been Bleeding Consistently

I have the nexplanon implant and have been bleeding consistently for 3 weeks now I do believe it is beginning to make me dizzy and tired on regular basis last time I expressed my concerns of irregular bleeding to my doctor she but on a low dose pill form of birth control to regulate that but I feel the excess of hormones may have been unsafe to my mental health any suggestions on what I could do other than just having it removed
