Implant worries

Hi everyone!
I just thought i would ask and see if anyone is in the same position as i atm.
I am with my bf now nearly a year and before i use to be on the pill but i changed to the nexplanon implant. Recently i seem to have no sex drive at all and i always just seem to not be in the mood. I was wondering is this an effect from the implant. When i was on the pill my sex drive was fine. Just thought i would ask and see if anyone has any tips.
