yeast infection 😞

So i’m about 5 weeks pregnant & ive been having this yeast infection for about a week now i called & emailed my obgyn & my regular doctor, my regular doctor at the beginning when i first got it said to just eat greek yogurt & i have. but my yeast infection has been getting worse & the itching is so bad i just feel so uncomfortable. but no one has gotten back to me. this is my first pregnancy btw. does anyone know if there’s anything i can take that’s safe while pregnant? or does just continuous eating of greek yogurt actually help?
