New spider

I got my first spider in the mail today. Once I got her into her enclosure, I misted some water (which she drank immediately) and put a mealworm in her food dish. She doesn’t seem to be very interesting in eating though. Should I be worried or does she need more time? Her abdomen is more on the hungry/small side right now according to a chart I saw on this subreddit… of course it’s a new environment for her and she’s probably stressed but I want to make sure it’s normal😅
