Toddler won’t eat after stomach bug

So on Sunday my 3 year old daughter had the stomach bug, she threw up 8 times. The next day no vomiting but had a low fever, ate some chips and drank a little. Since then she has barely eaten anything. All my safe foods that I know she loves, she won’t even touch. She hasn’t had any substantial amount of food since last Friday. She says she feels okay but all she wants to do is lay down. She won’t even play. Just wants to lay and watch movies. She’s not usually a napper and she napped for nearly 3 hours earlier (woke up at 4:30) and is already laying down saying she’s ready for bed (7 p.m). It’s so not like her. Should I call the doctor? Or maybe give it til Monday and see if she’s doing better? Has anyone else’s kid had a hard time getting back to eating normally after the bug??

I feel so bad.
