Congrats, Charlotte!
As you know, women are tougher than men. 🤣 Please don't ban me; I'm kidding!
Now that you have started injectables, your levels will rise. What people forget is that the hormonal changes we seek do not start with the first dose. When they talk about changes happening after six months, they mean six months after your levels are high enough to be in the female range.
So you are on your way. You will start noticing the difference, but it will be slow and gradual. Take some measurements and/or photos and then compare them six months from now.
And you could be right about your body processing things differently. One of the reasons I switched to injectables is that my body is a fast metabolizer. So pills and patches were not keeping my levels high enough, long enough before being eliminated. So, even after six years on HRT, the first four really didn't count much.
This is exciting! Just monitor your levels and see where you are. You are on your way.
