Levonorgestrel
birth control
"The mirena iud has changed my life. I have PCOS and was having really embarrassing, random, and prolonged periods. My doctor suggested the mirena IUD. As a woman  that has never had any children, the insertion of the device was excruciating. However, that should be expected when you think logically, having a foreign object inserted into your uterus isn't exactly natural lol... I had random/light bleeding for about 6-8 weeks after I had it inserted. Insertion sucked, give your body TIME to adapt. This IUD is the best thing that has ever happened to me. I've had it for almost two years now and I SWEAR BY IT. Patience to let your body adapt and you will NOT be let down."
