Just gotta say that despite being more "localized" in a way, Mirena's hormones can absolutely cause issues. I had it inserted in January and only kept it a few weeks. I'm not 100% sure what was from Mirena and what was from depression, etc., but I know Mirena worsened things for sure with mood and energy. I bled for 3 weeks+ straight on it, and I know that's supposed to be temporary and may've gone away, but it also caused worse cramps and lots of back pain for that time.

Anyway, I was actually just discussing Novasure with a friend today, and I'm kinda in the same boat with ya, unsure what to do. Good luck either way, and I hope things work out for you soon.
