A month on and cervix still feels sore

When I had sex before getting the IUD having my cervix pounded was the absolute best feeling (I have never had kids BTW). Now a month on I'm still sore and whilst most of the pain goes within a couple of minutes of gentle penetration, I just find myself unable to enjoy it the way I used to. It's still sensitive. Will it stop being so sore and will I eventually enjoy it again?
