Possible IUD?

I’m considering getting an IUD (specifically Kyleena) and have some questions for the masses that the websites don’t answer to help me make a decision... does it hurt when it’s inserted/removed (scale 1-10)?

What kind of side effects did you have?

Are you happy with it?

Are there any downsides?

How effective has it been preventing pregnancy?

Does it effect your mood?

This is a big decision in my eyes and would like as much help as I can get :) thank you!
