Nonstop period with Nexplanon

Hey ladies,
Anyone else out there have the Nexplanon implant? I got mine put in mid-January while on my period. When I got my next cycle in February it seemed lighter which was awesome, except it hasn't stopped since. I've been bleeding (not heavily, but consistently) since mid February & I'm just annoyed by it. Am I the only one experiencing this side effect? I've seen my doctor and she said it's totally normal, I just feel alone in this. 
Please help.
