IUD or arm implant?

B. • Mom to a loving and joyous baby boy ✨

Hey guys so I’m set to get on a new birth control next week but I’m still comparing the IUD and arm implant. What are your experiences if you have any with either? Side effects, pain, etc. I’ve been hearing the IUD is good but I’ve also heard horror stories but that’s with any birth control i suppose 😭. I’ve tried the patch, the pills, and depo already so those aren’t an option for me.
