abnormal uterine bleeding
"I have dysmenorrhea. I have had Mirena for almost 5 years, due to get a replacement at the end of this month. It has been great - no periods, increased libido. I did get some angry red pimples on my chin, which cleared up with antibiotic cream from my GP. Have gained weight, but this is undoubtedly due to my terrible diet and lack of exercise! My GYN said I could leave it another 6 months, but I have been feeling moodier/libido decreasing the last couple of months, due to the hormones waning. Mirena is the best thing I ever tried, I got it to try and stop my very painful periods, and it has worked!"
