I've had the mirena for 3 weeks. I got it when my non-hormonal IUD was starting to fall out, and my new doctor really pushed mirena on me. I was sure my insurance would cover it but, surprise surprise, I was billed a hefty $1,000 for this little thing inside me that is making me crazy!!! I have not stopped bleeding since it was "installed"--THREE weeks ago. I have backaches, headaches, and though I have not noticed any weight gain, I haven't noticed any loss either (even though I am at the gym 6 days a week and chasing around an 8 month old baby all day, you'd think I'd drop some pounds by now!). I have no sex drive anymore and though I have never been an emotional person, I am weepy all the time. My old IUD never made me feel this way, and I would NEVER have gotten a mirena had my doctor not absolutely insisted it is the "best form of birth control on the market". I'm so frustrated because I just got the mirena, haven't even paid the bills for it yet, and to remove it will be another huge bill I'm sure!
