Crazy emotions with Nexplanon!???

I had my implant put in about 2 weeks ago and this past week has been ridiculous. I've been going through some emotional life adjustments recently but I've been able to keep pretty good control of my emotions until this week. I literally cannot stop crying and it's in reaction to the slightest things or even just randomly. I have also been feeling very nauseous and not wanting to eat ANYTHING but carbs.  Could this be because of the hormones in my birth control?
