Ok I need pros cons reviews on IUDS!

I’m 37 weeks with my fourth baby and I’m just so hesitant on tubal ligation. So my doctor really wants me on the mirena but I don’t want anything hormonal as all those side effects love me so I was reading up on the copper IUD

what’s everyone’s thoughts?

Who has low dose or no dose of the IUDS and have you had any complications?
