Last month on the 18th marked one year with the Arm implant, and I can't even explain how AMAZING it is, and how my experience so far with it has been great. Within the past one year ic only had 3 period all there regular, no crazy mood swings, no weight gain, no breakout, NOTHING. I love it and it works wonders 😁 I recommend it, but don't forget every body is different.
