I've used hormonal IUDs since I was 16, and they've fantastic. You can just have one inserted and then not have to worry for the next ~6 years. Completely stopped my period too (came back briefly before I got on T, then T stopped it again, and now it's still gone even after being off T for several years). I can not overstate how amazing not having a period has been for my mental health.
When I first tried to get one, my doctor tried to convince me out of it because I was "too young" and hadn't had a child yet. I'm so glad I stayed firm in my decision and got a gyno who would work with me.
Yep. When I got my first IUD in, that was some of the worst pain I had experienced in my life. Felt like I was getting stabbed in the cervix, and the cramps afterwards were so bad I puked. Totally worth it, but I wish they had prepared me more beforehand (said I would feel a "pinch").
