IUDs hormones or no?

Having issues with making a choice on one, I have a 15month old and am done for a good while. What iud did you choose and how has/did it effect you? I am on the pill now. I had the mirena put in 6weeks after baby but had it removed after weight loss came to a stand still while breast feeding along with a lot of issues with ppd. Any chance that now mirena would work for me after being on the pill? Or would paragard be a Bette option? My periods were never horrible before baby or birth control.
