Spotting at 4 months with birth control implant

Apella • Living life & eating food.
Hey you guys! 
So the week before last I spotted for a week. I looked up online that it's a normal side effect of the implant, and some women even bleed for months and months. However, I just started spotting again today. I'm assuming it's normal, but I'd just like to be sure. 
p.s. 
I tried to make an appointment with the gyno, and by the time I go, I'll probably stop bleeding by then. 
Help? Anyone experienced something like this?
