abnormal uterine bleeding
"So after 17 years of horrific monthly periods due to my endometriosis, I finally had enough. I have "Microscopic Endometriosis", surgery won't help. 

So after everything, my specialist recommended an IUD. I was very skeptical, because I have tried hormonal birth control in the past and it made me really moody, with insane mood swings that cost me the love of my life. But after consulting with multiple doctors, they explained that the hormones are directly in the uterus and don't affect your moods. At first, I bled for like 2-3 months. It was awful. The pain was awful. But I stuck it out, it was my last option. I'm so thankful I did. After 6 months, periods stopped, pain stopped and my life has been pain free for 5 years. Love MIRENA!!!"
