Hey mama! So normal yan sa Implanon, marami sa amin mum friends na nag-Implanon at irregular ang period nila, some nag-stop completely, some nag-spotting lang like you, kaya don't worry too much. Pero since almost 2.5 years ka na rin, best to check with your OB just to confirm everything's still okay and if you want to replace it or try something else, they can give you peace of mind din!
