New to IUDs!

I'm currently pregnant with my 2nd baby girl, but after this one my husband and I have agreed no more children. So I'm looking into birth control. I've used pills before but always forgot/missed some. Don't want implant or shots. Don't want to always bother with condoms or rings. So can anyone educate me on IUDs? I've looked them up a bit, but I'd like more personal stories.
