Levonorgestrel
"I got the Mirena March 2015. My doctor informed all of the symptoms I would probably get during & after the procedure. The procedure was 10 minutes really easy. & I went straight to work after. I didn't really bleed which was weird since I've never been pregnant. After a month and a half I started spotting. This went on for like 4-5 months. sometimes it was daily other times it was barely anything. It honestly sucked but my doctor did mention that to me before my procedure. Now I love it. My periods are either super light or nothing. I would recommend it to anyone who doesn't like periods, & wants contraception lol. oh & I only gained like 3 pounds for how much craving I got"
