I had my out of date implanon implant out a month ago, when should i expect body to be back to normal? implant was in 3 years over what it was meant.

Your body is already: Since the implant "was in 3 years over ...", its content of the progestin hormone was probably used up and therefore you have had your body "back to your normal" all that time. Consult your gynecologist if you are concerned about your menses, pregnancy or need another effective LARC (long acting reversible contraceptive) like Implanon and set your "reproductive health plan" with that clinician.
