Hi S.,
I don't know if I am the one odd person out there, but Mirena did not work well for me at all. I am assuming that the other post today about airborn is also from you and that you are breast feeding. If this is incorrect, you may want to disregard what I have to say. Some background on me: I breast feed my son (now 3 1/2) for just over 2 years and had no supply issues with my breastmilk. Now with my daughter (now 6 months) I got the Mirena put in about 7-8 weeks after I had her and I have had some major supply issues. She is a great eater but my supply has greatly suffered throughout the 6 months. I have been working with a lactation consultant and the only thing that we can figure is different between my son and daughter while breastfeeding is the mirena. My diet is the same. A few weeks ago I started to feel like I was getting my period and my milk supply almost went completely away. I have had to give my daughter anywhere from 1-4 bottles of formula each day. I had the Mirena taken out about 3 weeks ago because of my supply issues and I am still having problems with my supply. I really don't have any idea if the mirena was the cause of my problems but I can not figure out what else it might have been. My OBGYN claims up and down that the mirena should not have made a difference. Also, sex became very uncomfortable after my daughter was born, it hurt. I didn't know what the issue was, but since I have had the mirena removed sex is back to normal and does not hurt like it was. So, I don't know if I am the abnormal person out there with a reaction, but it sure didn't work for me. I would suggest that if you want to go the IUD route try the non-hormone 10 year version and I wish I had. Or wait until you are no longer breastfeeding.
I hope this helps and whatever you decide works for you!
