Birth control

I go next week for my 6 week postpartum check up and will be going back on birth control. I was on nuva ring before we decided to try for a baby and I liked it but it seemed to make my already low sex drive even worse. Im 21 so I should have a very healthy libido but I just don’t. I had the nexplanon in the past and didn’t like it but I also gained weight on it which is the exact opposite of what I’m trying to do. What do you guys have for birth control that you like? Picture of my little one so we don’t get lost!
