Birth Control after baby

Tabby • • Happily Married • Mama of two💙💚
After I have my son I want to get on birth control, I've already been on the pill before and constantly forgot to take it. I would like to try the patch or the IUD. Can anyone give me their recommendations and if you've had either can you give me symptoms you've encountered from the birth control and how you felt when they put it in (IUD)
