Mirena: yay or nay?

Sydney
So I had my postpartum appointment today. I decided on Mirena for birth control because the mini pill just scares me in terms of effectiveness. But now I'm a little worried about the complications, especially the ones that could cause me to have infertility problems when I want more children. Anyone have Mirena and have no issues getting pregnant? Anyone have problems? I would love to hear any and all stories (good and bad). (Btw I already got it placed today)
