Non hormonal IUD- anyone have one?

Hey ladies. I'm almost 6 weeks postpartum and my doctor is asking about birth control. I was on bc pills before we got pregnant and they made me crazy (tried two different kinds), so I didn't want to try them again. Dr. recommended against the shot because it can worsen depression and I already have pp depression. 
In the end, he recommended a non hormonal IUD (Paraguard). Anyone have one or used to and can tell me about their experience? How does it feel getting it inserted? We're wanting to space our kids out 2.5-3 years or so, so I feel somewhat okay getting one in the meantime. I heard your periods get heavier, but that's the only side effect.
