I know lots of women, myself included, who haven't had kids and who had one fitted. My GP was telling me that it's an extremely popular contraceptive method in Scandinavian countries for women who haven't had kids. It's meant to be more painful if you haven't given birth but tbh I found it alright. Bit of abdominal pain afterwards but nothing Jack Daniels couldn't fix Some GPs don't like to fit them because it's still relatively rare and they don't have much practice at it - mine sent me to the Well Woman instead.
Does anyone really want to take contraception advise from someone called Juno?
