So, I had my Mirena removed almost 2 weeks ago now and immediately started taking Yaz. I will miss the fact that I haven't had a period in about a year and the ease of not having to remember to take anything but the acne got too much to bear. My reflection caused me to cry and I couldn't seem to shake 8lbs, and I workout all the time, we're talking 3 times a day, 3-4 days a week, so it wasn't due to my lack of effort. And my diet is phenomenal, it was all very disheartening. I even made peace, finally, with my larger self but my acne was just unreal! After reading the other experiences on here I was simply reaffirmed about my personal suspicions and had a scheduled pap so I told my gyno to remove it. She completely agreed with me, saying that she's seen an increase in these types of cases over the last year, (one resulted in a 40lb weight gain and after removal 20 lbs dropped over several weeks!). She is a wonderful doctor. She said that IUDs have been relatively unused in the states until recently so we simply lack the data for longer termed effects and that since she's come across so many of them lately that she makes sure to inform all of her potentials of them. Mirena works for a lot of women, I have friends on it that swear by it, beautifully clear skin, but they have also seemed to gain that 5-8lbs that's unshakable, but I'm sure they don't associate it with the IUD, like I didn't at first either, but it was irremovable! Anyways, my doctor said it best, Mirena works for a lot of women, but not one thing will work the same on everyone, just as my side effects were pretty common but some of the effects on here were WAY different than my own experiences. All I can say is that I'm glad I didn't have a nightmare of a doctor like some of the other ladies here. If you are referencing this site and are wondering if your effects will go away, I had my Mirena in from Oct.07 to Feb.09. About Jan.08 I started breaking out, not that I ever had phenomenal skin, but these were cystic almost, different than normal acne, but my weight was unchanged. About July08 I noticed a little weight gain but had been on a couple vacations and was about to take a sabbatical, all likely reasons, but I can drop any holiday 5-10lb weight gain within 2 weeks due to effort, but not the 8lbs I gained then, as of Feb09 the acne had persisted and increased, new ones popping up everyday around my chin area and jawline ( not ever before), some on my back (also not ever before) which, after further research, found that those areas around the chin break out usually due to hormonal effects, and then I just finally couldn't take it. I looked in the mirror one day after work and just started crying. My reflection was horrible, my self esteem was diminishing and no amount of my wonderful boyfriend's admiration could make me look any better :( I can say I'm seeing a difference in my skin now on Yaz and am simply hoping there are no nasty side effects waiting in the works for me there! I hope this helps someone out there like so many other testimonies helped me!
