Getting IUD in an hour. How bad is it?

I’ve actually been shaking for like an hour I’m only 17 I’m seriously so so anxious to get this everyone IRL has told me how they’re scared for me or wishing me luck and online people have said they’ve passed out from the pain or screamed or had it taken out like I’m so so scared 😭😭 please does anyone have any advice they wish they had when they got it. I’m so scared to get my cervix PIERCED agghhhh and I’ve never had a doctor or anyone look down there before
