Should i be worried?

Adia

So i started these new meds about a month ago...and my doctor told me they may cause a SLIGHT loss of appetite and chances of weight loss but he said “nothing too drastic” but ive lost 15-17 pounds..im 14 and im 5’3-5’4 and i was somewhere between 155-160🤭 but now im about 145 and i havent worked out or anything...should i be worried or happy? And i went almost an entire week without eating and i didn’t notice because i wasnt hungry but everyone was freakig out...🤷🏽‍♀️ what do i do?
