How is she doing?
Is she pooping? Do you have photos of her and her poop?
If you think she may be struggling with expelling an egg or egg material, get Calcium into her asap. You can find Calcium Citrate+D3 at stores like Walmart, CVS, etc. Give one tablet now, then once daily for 7 days.
Work on hydration. You can give electrolytes or sugar water. I would omit the vinegar at this time.
I assume pet RV is VetRx? While VetRx probably won't hurt, it more of a product like VaporRub to help temporarily alleviate respiratory symptoms.
