IUD or mini pill?

Stephanie
I am 37 weeks with my fifth baby, and I am starting to consider birth control. My hubby and I have never really used it, and we will now have five children eight and under. I'd like to give my body a little bit more of a break if we decide to have another one. I asked my midwife about the mini pill and she says that it is good, but should really only be used when breast-feeding. She also said IUD's are really popular, but I'm just not hundred percent sure about them. I would probably be interested in Mirena or ParaGard. I guess I am just curious of everyone's experience with any or all of these options. Thanks!
