Yeast infection medicine and breastfeeding

I’ve been prescribed terconazole for a yeast infection because the pills didn’t seem to work. I’m breastfeeding. My doctor knows this and still prescribed the cream anyways. I was just about to use it and I decided to google if it was okay to use while breastfeeding. But it says it hasn’t been studied. It’s Saturday night. I need to start this med now. Doctors office isn’t open til Monday. Pharmacy is closed.

What do I do?
