If you are referring to Mirena, I LOVED it at first - how could I not? I didn't have to worry about a pill, and I never had a period! It was great! Or so I thought. I wish I had had all the info myself before making the decision to get it. Even so, I probably still would have gotten it anyway, thinking I wouldn't have the side effects or I'd take my chances. But at least I wouldn't have suffered so long.
So, before you get it, please be aware of potential side effects. Four friends and myself have all had it placed, and only one has not experienced any side effects. In fact, the four of us that had problems were so displeased we had it taken out before a year even went by.
It only took about 10 mins to insert, and there was mild pain during, like a pap smear. Some very mild cramping and spotting followed over the next week. But over the next few months, I started to experience these side effects (and I know it was definitely the Mirena because they've all subsided since I've had it removed): 15 lbs weight gain, excessive bloating, excessively greasy skin & scalp, horrible acne, low energy, low sex drive, mood swings and irritability. No amount of dieting and exercise helped, if I even had the energy to exercise. Almost like what I experienced when I was pregnant, but times ten. Because I had had it inserted as soon as possible after I gave birth, I blamed myself for not being able to shake the pregnancy side effects, and couldn't "snap out of it." Because the Mirena prescribing info doesn't even mention any of these side effects, I never even considered it to be the cause. Luckily my husband actually did think it was that, and did some research. Here's one of the forums he found for me: http://www.aippg.net/forum/viewtopic.php?t=24435&post... (Even though I had no periods, one friend had heavy heavy long periods and awful cramping.)
So I did some thinking and decided to have it taken out. That very night after it was removed, my emotions were clearer - it seriously was almost like a cloud had been lifted. Even my senses, touch, sight, smell, hearing, were clearer, like they'd been suppressed all that time. And I was suddenly attracted to my husband again!
I'm not trying to discredit the Mirena IUD, It does certainly have pluses: it doesn't take long to insert, it's VERY convenient, if your insurance covers it, it's much much more cost-effective than the pill, and - luckily for people like me - it's super-easy to remove.
I'd say it's worth the try because you can always have it taken out at any time if it doesn't agree with you. But if it's not covered by insurance, I wouldn't take the gamble (it was about $1100 total).
Hope I've helped you L., and anyone else thinking about it!
