Iud appointment nerves

I have my appointment in a few hours and I'm terrified I'm ngl. I was hoping some people might have positive stories about the insertion process, specifically, if you chose to stick with topical numbing or get a lidocaine injection. I have never had a pap smear, iud, or any doctors all up in my business so this is a very new experience for me. 😅

I have heard horror stories about the lidocaine injection hurting like a bitch and I'm already nervous around needles so I plan on going with just topical numbing. Am I going to regret that??
