My endo effectively leaves it up to me whether I start progesterone now, 1.5 years into HRT. What I could find online suggested that starting too early could have negative impact on breast growth, so I said no at this point since I haven’t yet seen as much breast growth as I would like.
Should I be starting after 2y? Should I be contacting my endo to change my mind and start now? What’s the wisdom?


Transfem Science would be the most authoritative, they have great info on medication.
Thanks, they don’t really have much to say about the timing unless I missed something with my ctrl+F but it is a wonderful resource!
unfortunately I think the reality is that nobody knows 🤷♀️
