Help - using iud as emergency contraception

I’ve been wanting to get an iud for a while. But recently I had sex and the condom broke and his cum definitely got in me. While I was going to take the pill I figured I might as well just get the iud if possible within the next couple days.

I see that I need a copper iud to make it effect as plan b too.

Anyone know anything about this? Any info would be helpful and so would opinions and experiences from people with the copper iud
