Well, I'm only on thyroid hormone replacement therapy because of Hashimoto's. My gyn would like me to take hormones (estrogene, I suppose) as well because of the endometreosis but I don't want to. Twice in my life I was on birth-control pills and each time, I became depressive. I think it was the estrogene that caused it, my hormone levels are just too messed up to deal with it. So I'm really careful when it comes to hormonal replacements.

A couple of years ago, before Hashimoto's was diagnosed, they gave me gestagens when I started feeling ill, and I gained a lot of weight from it (and later from the thyroid hormones as well).
