Yeast infection??

I think I might be in the beginning stages of a yeast infection😭 my discharge has been kinda thick and white for two days but no itchiness. This morning I had just a little bit of itchiness but nothing uncommon. It’s also a week before my period which is usually when they hit. I haven’t had an infection in about a year.

I have a little tube of Monistat cream left over from my last infection. Is it safe to use it as a precaution?

Sorry if I sound like a hypochondriac 🙈
