Weight / Fat loss

I see what you're saying but happily that 'occurrence' doesn't happen to me. I'm special. I have an injection to stop it. (It also stops babies. It's very convenient.)

Well, if you are concerned about your body composition and particularly fat. You may want to look into the effects of extra lady hormones. But your situation should mean that anaemia is pretty much impossible.

Also, wikipedia says this about progesterone;

It may affect gum health, increasing risk of gingivitis (gum inflammation) and tooth decay.[citation needed]

Which again might be meaningless as it doesn't even have a citation, but there you go.
