abnormal uterine bleeding
"I had Kyleena inserted in Dec '16. Insertion was painful. No pain once it was over. I have PCOS, but cannot take estrogen; my doctor recommended a hormonal IUD to help thin the uterine lining to protect from future cancer. Began to spot a few days after insertion; after a few weeks it turned into a light period for 4 days, then back to spotting. Another light period at the end of Jan lasted 2 weeks. Then more spotting. End of Feb spotting ended and I was finally spot-free for 2-3 weeks. Then, another light period for 2 weeks. Then spotting for about a week. Now spot-free again. Periods are extremely light. Spotting annoying, but I hope it tapers off eventually. Can take 6 months for body to adjust. Acne bad first 2 months then back to normal."
