I've read that too much estrogen can be converted into testosterone. Maybe your dosage is too high? I'm hearing the word increase and it's making me cringe. I'd love to have more estrogen, but how effective is it given the above?
Another thing to consider is maybe measuring with a loose/clothing measuring tape to stay more objective. I've looked at myself and say "Wow, I am developing really well", but checked with the tape... all in my head, and I was very amazed. I could easily look the next day or measure another time and say "Woah... What happened here? Why did they reduce?" even if nothing happened. I'm not saying that your situation isn't happening to you, but being more objective has kept me from panicking (or kept it at a low), and the information is useful in my opinion. I hope to report it to others in the future to explain how the progress may work, and I'm looking for possible correlations should any exist.
Have you had any recent changes in your eating routine, or are you keeping track? Exercise? This makes a difference even in cis-women.
I hope this may spark some helpful ideas!
