birth control
"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."
