Debating on getting a copper IUD

I’ve been thinking about getting an IUD for a while now and i am leaning toward a copper one. However I’m really worried about all the possible symptoms. Ive been online that sometimes periods get heavier and cramps are worse and people get lots of acne and all that from it and its making me wonder if its even worth it. My boyfriend isnt a huge fan of my getting it but only because of the pain that comes the day of or couple days following after insertion and all those possible symptoms. I’m 21 and a student, not sure if that matters.

So basically, what is your personal experience? And what are the downsides you’ve personally experiences and is it worth it?

Ive obviously seen everything that is stated online but those are general symptoms and all that and not specific at all.
