Paraguard birth control opinions?

I had my daughter three weeks ago and will go for my post partum appointment in two more weeks. It took a long time for us to get pregnant with her so I'm very wary of birth control now. I was on the depo shot for several years and hated it and then the nuvaring which I liked but it seems any hormonal birth control like that kills my sex drive. I was considering natural family planning until I read that the failure rate was 20%. We want to have one more but not for a couple years. I'm thinking the paraguard iud may be a good option since it is non hormonal. Any opinions from those who have had it before?
