Yeast infection/pregnancy

My doctor said I was positive for yeast, but I literally have no itching and no odor or clumpy discharge...

I HATE using monistat because it makes my vagina feel like it’s burning off and has caused actual chemical burns before. He says that’s the only thing I can use though. What would you all do? Can I even use the 3 day monistat or only 7 day? Even using the 7 day one was is awful for me and burned my vagina. I kind of want to just eat a bunch of yogurt for a few days and let my vagina air out considering I don’t even have any symptoms anyways.
