Progesterone trial and error queries and tears

Hi hi

So I am newly 40 and was put on progesterone by a physician who seems to put all "around 40-year-olds" on it to help combat any perimenopause symptoms.

Not in estrogen yet.

I have been on it a month and feel fine but I do notice a "waterbed" like weight gain around my mid-section

I went off of it to start my period, as prescribed, and though I've only been off of it for two days, I feel like I'm dramatically depressed and emotional.

Is this normal?

I'd like to stay off of it as I didn't like the sudden weight gain but will this "blag" feeling fade and when?
