Nexplanon Impant concern?

Alexa
So I've been on the Nexplanon for the past 2 months. I was supposed to start my period on the 16th of this month, I've been spotting since then and it is bothering the shit out of me. I know the side effects are spotting but would it be like this? My first period on it was fine, it was regular this second one is me spotting for almost 2 weeks. Someone please give advice.
