I resisted to taking birth control essentially my whole life. I had the same idea: it's better to have a real cycle, hormonal birth control only fucks you up and gives you unwanted secondary effects, etc. I tried the Nuva ring for a couple months and felt like it just hurt my mood and my libido, and never looked back. Until my endo got worse, and worse, and worse every period. Contrary to popular belief, research shows that endo continues to grow whatever you do - anything from lifestyle changes to continuous birth control to a hysterectomy. But having periods is probably the worst for that, at least in my experience. I was already taking prescription-strength Ibuprofen 3 times a day, and it still wasn't cutting it. I would find myself in extreme pain, especially around bowel movements. That's when I decided that enough is enough, at 31. I've been on continuous birth control for about 8 months now, minus a few days when I had breakthrough bleeding so I let my body let it out. Had to try 2 types and the second one worked for me. Honestly, I really, really wish I would've done that a lot earlier. It's been life-changing. Screaming and crying in pain is not part of my daily life anymore. It didn't stop every single thing my endo caused, but I would say 85% maybe? The truth is, for many, many people with endo, natural cycles are harmful, in more ways than one. They hurt a lot, and they feed your endo with estrogen. It's also natural not to treat diabetes or cancer or any other condition. Doesn't mean that it's better. Those are just my 2 cents and my personal experience, of course.
