Birth Control

Molly
Ladies!! Which IUD should I get??  Copper, Skyla,  Mirena or Liletta ? I don't want the pill or Nexplanon (arm injection). Thanks! It doesn't matter how many years it lasts for me; I just dont want kids for about two years or so, for now. And I don't care about getting a period of not, I'm more worried about weight gain and and hormones. 
What are the side effects, pros/cons etc. of any of these? Which one would you personally prefer??
