First well done for getting a blood test. But second, and as no one else has said it yet, PLEASE find a therapist or doctor to supervise you. Please don't self med.
Self Med can be really dangerous. I mean even if you get a blood test will you be able to interpret it?
You NEED a supervising physician. Actually strictly they don't even have to be a gender specialist. Just a sympathetic doctor. But personally I would suggest that if you are going to do this you should do it properly and go see a proper gender practicioner.
Self med may seem like the easy option at first, but later on when/if you want to progress further and start thinking about various surgeries etc you may find that having bucked the system leaves you even further back than you were before you started - because now, to get that all important referral letter, you will have to deal with a therapist who feels irritated that you broke the rules...
