What's it like getting the Mirena?

Hola ladies. So I'm about to get the Mirena IUD as my physician and I deemed it the best birth control option for me. I just wanted to know if anyone of y'all who have gotten it have any advice and can tell me what I can expect when I get it. He prescribed me some pain medicine to take beforehand but I'm not a big fan of drugs so I just wanna know if can manage without them. Thank you all!
