Nexplanon

anyone else having a horrible Nexplanon experience? 
my first year having the implant I didn't bleed AT ALL.. Now, I will have my period for 2 weeks, be off for 4 days and then bleed for another week. And I usually always have a small slightly brown (blood) discharge. 
I'm starting to want to rip it out of my arm :( anyone else experiencing this? any advice?
