Birth control : IUD Vs Depo shot

Hi mummies! For those who have been/are on birth control and have tried both IUD and Depo shots , care to share the costs involved and how was your journey with these 2 methods? I just gave birth a month ago via c sect and am looking into these 2 choices. My gynae has advised me against the pill as I'm currently breastfeeding and gave me a choice between this 2. Was wondering what are the pros and cons. Not planning to have another at least until another 3 years or so as I already have a 3 year old and newborn. 😅 Looking forward to hear your inputs!! Thank s in advance
