Postpartum contraceptive

Kia
I'm debating on what birth control I'm gonna get at my 6 week check up. He offered IUD, depo, the pill and a few others. I'm leaning more towards depo being that I don't want anything inside of me and I'm too forgetful to take pills everyday. If you got the depo how was it for you after birth? Did you gain weight? did it make you sick at all?
