the pill

Destiny
Okay so I have my 6 week postpartum checkup Wednesday and hopefully I'll be getting on birth control. I used to be on the nervaring when I took it to regulate my period. Now I need it to prevent pregnancy. Well I was thinking about doing the pill but I'm afraid of the side affects. The ring made me gain weight and I don't want that to happen again. So if you are on the pill or have ever been can you let me know what side effects you have or had and did it make you gain weight
