I've had my mirena for almost 3 years. I decided to get one when my last child was 6 months old, in Oct. of 2006. My CNM assured me that it was a good choice for me, even though I was breastfeeding. For the past year, I have not been able to find the strings. I read that sometimes they can soften up and curl around the cervix, but they are NOT there. I imagine they must have moved up into my cervix or uterus. This scares me a lot. Along with that, I have had many side effects, and I've noticed they have gotten worse as of late.... -Hair loss, oily hair, dandruff, weight gain, oily skin/break outs (I stopped having breakouts once I hit my early 20's and I am 29 years old with pimples again). Terrible mood swings, nausea (as of late), fluttering/spasms in my uterus (as of late), heavy breasts (as of late). I'm actually thinking about taking a preg. test tomorrow to make sure I'm not preggo, that is how bad my symptoms are right now. I have not had a period in so long, I'm not even sure when the last time was. I'm going in a few days to see about having the mirena removed. I'm very nervous because I don't even know if it's still where it should be. As far as BC is concerned, it's great, because I can't remember to take a pill, but it isn't worth all the other things that come with this IUD. It's mindless BC but it's also worrisome for my own health BC! At this point, I'm thinking about getting rid of hormonal BC all together and using a diaphragm and practicing Fertility Awareness. I'd rather take my chances with something that is not going to make me crazy, sick, or put me at the possibility of major surgery/loss of my womanly parts.
