IUD birth control

So I will be having my four week postpartum checkup next week but I thought I would get some other people’s point of view if they have used the IUD for birth control. I just had my fourth baby, I don’t think I want anymore but I’m not quite ready to get my tubes tied. What are some pros and cons that come along with it. I used the patch it the past and was happy with it but the IUD seems like a better option this time along. I’ve heard and read different things and I just want to be sure it would be the right decision for me. Thanks!
