Not sure what’s wrong with my goat.

Hi everyone, I’m new here. Someone from BackYard Chickens recommended I post here. Anyway, my goat Missy she’s a little over 5 months old.
Last night, she was very weak and in pain. She hadn’t moved out of the same position for more then 3 hours and she hadn’t eaten since the day before.
I’m wondering, could this be worms? Could it be an upset stomach? She hasn’t vomited and no diarrhea as we could see and no blood in the stool.
This morning, she’s a little more active, but unsteady on her legs and can’t stand that long. She did eat some grain tho so I’m guessing that’s a good sign.
She doesn’t appear to be in pain like she was last night. Her eyelids are a dark pink. Her breathing seems normal and her stomach does not appear distended.
This is my first time raising goats so I honestly don’t know what to do right now. I am going to try and get her to a vet ASAP but in the meantime, figured I’d post here for any advice you might have. Thank you.
