Mirena?? do you love it or hate it?

I'm having my daughter next Thursday & my doctor told me to try to decide what birth control I want when I come back for my follow up. Since I'm breastfeeding my options are the mini pill, iud, or depo shot. She suggested the Mirena & said I could get it placed at my follow up if I wanted. I'd like to know you all's experience with Mirena & how was the insertion for you? Was it painful or what? Thanks!
