4 years with the Mirena - when should I change it?

Kate • Mirena user 🇨🇦

So I got my Mirena in August of 2015. I know it lasts 5 years, but it’s not an exact thing. When should I get it taken out? Can I put a new one in right away or do I have to wait? Has anyone swapped them immediately before? What’s it like?
