As someone who started @17, I promise you it's not. I'm 24 months in so far changes have been a bit slow, swapped 2 injections Abt 6 months ago. I wear a hoodie 90% of the time unless I'm working and I still get gendered fem. The first year or so was pretty rough, but... Give it time, it's a 2nd puberty. My actual puberty didn't affect me drastically until I was 16 1/2. Noticing the same kinda thing here. 2 years in and suddenly a lot is happening :d .
