That seems like a well thought out decision. The idea that all nonbinary people are just binary trans on the pipeline can be a harmful stereotype, even if it is in fact true for some. I’m happy for you that you’ve found a gender that represents who you are.
Being nonbinary and taking HRT is an option, in case you were wondering. There’s no rule about how to not conform right! :3
In any case, hope your blood work went well!
