Switching to an IUD (Kyleena) from the pill

Shelby

I have endometriosis and I’ve been on the pill for 10 years. In fact, I was on the same pill for 9.5 years and the only major problem was that I got bad menstrual migraines. I finally switched to a female doctor who right away recommended an IUD. Scared, I opted for a different pill. Well this new pill somewhat helped the migraines but caused awful and extreme mood swings. So now my doctor has pretty much talked me into the Kyleena IUD. Should I be scared? Is there anything I should prepare for? TIA 💙
