am i too skinny for hrt?

I know this sounds so stupid and i’m probably just letting the worrying get to my head, but i’m underweight . I’m 5’4 and 90lbs and i’m nervous if I am too skinny to go on hrt? Do i need a certain amount of vitamins and minerals? Again i’m sorry if this is so stupid but i’ve been waiting forever for hrt and i need to know if this would cause me to have to wait even longer
