Hun please please check out
www.curezone.com and search mirena IUD, I had one put in 3 years ago, ended up with weight gain, acne, and severe depression (to the point of trying to top myself) which I put down to massive stress, parents going through a really messy divorce etc. I decided to get it out as wanted to TTC soon and wanted my body to be natural before hand. While researching how to get it out (I had it put in surgically while I waqs getting a laparoscopy and wasn't sure if I had to have it removed surgically) I came across cure zone. There are thousands of women who have gone through hell and currently a law suit in America to take the production company to court for not labelling all the side effects.
Anyway, since having the Mirena removed I have been fine, the depression is gone, my skin has cleared up and I am not PMSing constantly. I also taked to a mate of mine, and not two weeks after having hers put in she developed manic depression and bi polar. Had it out after I told her about cure zome...and shes doing much better.
I'm not saying to you don't do it, I know Mirena can work for some people, but please be aware of all the risks, even the ones they do not tell you about. At the end of the day it is your decision, but please just check out
www.curezone.com and have a look for yourself.
I hope you don't think I'm being horrible in this post, just concerned for you!
