Implanon or etonogestrel subdural can cause breakthrough vaginal bleeding as a side effect.
it sounds like you have not tolerated any sort of birth control well.
was your bleeding less on Depoprovera?
have you had your ferritin and iron levels checked to see if they are low?
so it is up to you if you stay on Implanon or go back to depo
it sounds like you still bleed or spot on either of these treatments.
let me know if you have other questions.
