What to expect at my first HRT appointment

I am 19 and I have my first appointment for gender affirming care later this month. I am super excited but I don’t know what to expect. Sooner of you may not know this place but it is in Indy and it’s called The Damien Center and they provide services to anyone who needs it. I wasn’t sent to do any lab work before hand and I just want to know what to expect when I get there? Any advice or comments are welcomed!
