Copper IUD works well for me (Paraguard). Drawback is heavy bleeding. Hormonal IUDs don’t last as long and have a higher tendency to migrate or allow ectopic pregnancies. Upside is, they can make your periods lighter or stop bleeding all together. But there are other side effects that come with hormones. Take into consideration how you’ve reacted to hormonal BCs in the past before getting a hormonal IUD. Both types are about equal in their success rates.
Oof. I highly recommend a copper IUD then. Reactions to hormonal bcs are often unpredictable. It’s one thing to try them with pills you can stop at any time, but IUDs are difficult and painful to remove. If you have no clue how your body reacts to progesterone and/or estrogen, it’s best not to gamble.
