What birth control?

Elissa
Okay so my postpartum appointment is in a little over a week and I have no clue as to what birth control I should get. Before my 2 pregnancies I had the Mirena for 5 years and that didn't go so well. It would hurt me and when it was removed I found out that one of the wings was damaged and bent so that is completely off my list. What BC do you ladies think is good.? I do have a problem with BC making me gain weight so I want something that won't cause that. Any suggestions would be appreciated thank you!
