abnormal uterine bleeding
"As a woman in my early 20s, I am too busy with school, work, travel and social life to begin worrying about having children of my own, thus why Mirena sounded so appealing; no daily pill, no irritating condoms, etc.  I am prone to UTIs, the ultimate reason I chose Mirena, which is the only pro to have come with this procedure.  Having had the Mirena inserted May 13, 2015 (the most painful procedure I have had yet), I have had MAYBE, and I mean MAYBE a total of 2 weeks where I did NOT bleed.  My doctor failed to mention this.  I have absolutely no desire to be intimate with anyone because I am so livid with the fact that the bleeding is so unpredictable. If I had not spent as much time/money as I had, I'd have it removed immediately."
