I am 40 years old, divorced, 2 children, in a monogamous relationship for 2 years, all credentials as a perfect candidate for Mirena. I originally decided to have Essure, but my doctors convinced me to wait a few years, as it is peramament, irreversible. So last week, after much research, through the internet, and friends, I had Mirena inserted. I was looking forward to the spontaneity, and done with the side effects of condoms, spermicides, and the like. The first day was not pleasant, I had a terrible migraine, back pain, and heavy bleeding. Since then, the side effects have come & gone from time to time. I have experienced nasal congestion, stomach aches, diarrhea, more migraines, and fatigue. I decided to give it more time, in hope the symptoms would subside. Until the other night, when my guy told me he could feel the threads, and it was quite painful. I am not sure why so many of us have all these issues. I recall from the early 70s, there was much controversy regarding the IUD. I thought the research and improvements would make it safe & risk free. I can only say, that based on my mood swings, bleeding, cramps, and now this sensation my guy feels, he described it as a mini electrical shock, I am regretful of my decision. I will make an appointment to have it trimmed, and give it the 6 weeks to see if any effects improve, or at least subside. I wish I had read these blogs before I hade Mirena inserted, I would have reconsidered other options. Thank you to all of you for your honesty. I empathize & sympathize with all of you. I will keep you posted throughout my progress. Good luck to all of you!
