When do actual changes start to occur?

So I (18 year old) have been on 2 mg pills of estrodiol for about 4 months now, and I haven't really noticed many changes aside from my chest growing out a bit (at least, not in the muscle and fat redistribution categories)

And I'm starting to worry I might not see any changes at all. I have quite broad shoulders, and I am quite tall, so I was hoping muscle and fat redistribution might be able to help with that, but I'm starting to get worried
