Hi alisando01

Implanon is considered safe when breastfeeding. The main problem is that there has not been much research into this method of birth control. However it contains the same hormone (progesterone) as the mini pill (which is commonly used when breastfeeding), and therefore it is expected to have the same outcome. Which is a small mount of progesterone in the breast milk. And now, many doctors will give women Implanon when breastfeeding
If the mini pill did not work for you then you could also consider Depo Provera, an injection every 12 weeks or so.
