Copper IUD

I plan on getting the copper iud right after I give birth in June. And I remember the Dr. telling me the best time to get the IUD was when I’m on my period because the cervix is dilated a bit to pass the blood.

I’m just getting more curious about the IUD.

Also if anyone has an experience with Copper IUD... how is it? Do you get a period every month?

Any unusual symptoms?
