I've had two in my life.

The first was copper (non-hormonal). Putting it in didn't hurt much. I bled almost every single day for the next year and a half. Cramping was bad. Removal was not terribly painful. 0/10.

Second has been hormonal. To be transparent, I have PCOS so I already did not have regular periods, but I haven't had a single period in 3 years now. I think I spotted once. I get cramps once in a while (though that could also be the PCOS). It didn't hurt much going in (though I had a bad experience with the male doctor/ptsd). Life has been so good, I forget that I ever even had periods to be honest. 10/10.

Both times I took ibuprofen before the procedure, but I know they sometimes offer stronger if you ask. If you're comfortable being on hormones, I do recommend.
