Implanon
"All was well for the first year and half. Then, it seems, my hormones got way out of wack due to the synthetic hormones being released by the implanon. I now have excess androgens and not enough progesterone. I gained 20 lbs (on a naturally thin, 5'4" frame) and, even worse, cystic acne (on formerly clear, normal skin)! I had implanon in for a total of 26 months. I've recently made the switch to a copper IUD and my hormones have not yet balanced out. I'm giving this a 4/10 because I didn't get pregnant and I didn't have side effects for the first year or so."
