Well we aren't allowed to give doses, but this is a reason why we should be able to do it. You are obviously on quite a low dose, going to a more regular dose. It is normal for doctors to start like that. I started on a VERY low dose and was on it for 3 months. I wouldn't say I had no changes but the changes were *very slow*. I believe you are going to start noticing changes, but if you look at videos on youtube you can see that a lot of times the changes don't really start happening until 6 months or later (despite all the little "I got a couple hairs on my stomach" comments). My voice really didn't drop til about 9-10 months. I didn't start getting read as male til maybe 4 months and it was maybe only 10-20% of the time. (Now it's about 98%-- I am reliably misgendered once a month.) But everyone is really individual. Now if you were two years vs 3 months, that would be highly unusual. My advice? Be patient.
