Thinking about getting an IUD

Cait

I currently am on the pill and I have an appointment next Wednesday to get an IUD insertion. I am worried about getting on though. I heard it’s been hit or miss. Considering it because there is a smaller chance of getting pregnant on it, no human errors like the pill, no outside factors can mess it up like medications. They recommend the Skyla for me. Someone help? Give me advice, thank you :)
