I’m finally getting my hormones! I’m gonna do injections, and my doctor said she’s comfortable prescribing me oral progesterone as well if I want it. And it’s a female hormone, so why shouldn’t I have it, right? I know it’s supposed to help with breast development, and maybe libido, but I haven’t done as much reading about progesterone as I have estrogen. Should I start it at the same time I start estrogen? Is it even worth taking? Would love to hear others’ thoughts and experiences

You're getting a lot of different answers here.

There's no guidelines or good research on this. Doctors recommend waiting anything from 6 months to a year and a half. Sometimes it's to wait until a later tanner stage.

Ignore everything else you hear. There is no more useful information. The recent study showing prog might help with breast size started after 6 months. Everything else is guesswork or anecdotal, and our anecdotal data is very much lacking too.
