P.F.
I love my IUD! I have a very busy life and that is one less thing that I have to worry about. It is much like the pill, so whatever side effects you have to the pill, that is what you can expect from Mirena. The only difference is that Mirena seems to be amplified. For example, I had extremely light periods while taking the pill. With Mirena, I have spotting every five months for one day and light cramping for one day a month, that is it. I don't get bloated or have the massive mood swings. It is great. I will say that the first month was the hardest. After insertion, I had cramping, bleeding and spotting for most of the first month. After it settled in place and they trimmed the wires, smooth sailing. I have had mine for almost five years now. I will be replacing mine this spring. I highly recommend it. Good luck and God bless.
