Issues with Nexplanon?????? Help!!!!!!!!!!

Hi ladies, I need some insight. I have had the Nexplanon implant for almost a year now. At first I loved it! I didn't have a period for 3 months. But since then, My periods have been so wonky. I'll spot for about a week and a half, bleed heavily for 2-3 days, then spot for another week and a half. And then it repeats anywhere from 2-6 weeks later.

Also, I feel like it's really suppressing my hormones. I am really bland and blah about everything. I don't get extremely happy, or sad. My sex drive also seems to have gone on an extended vacation.

Have any of you experienced anything like this with the Nexplanon? Or am I just suddenly a dud?

Any input or insight would be really appreciated!
