Help please

Im taking progesterone as a vaginal suppository. Crinone gel 8% to be exact and i am pretty sure im getting a yeast infection. Im itchy and really uncomfortable. My doctor isnt open until monday otherwise id call, but does anyone know if i can use monostat or something safely? I know its okay bc im pregnant, but in not sure if it matters that in already taking something vaginally. Thank you in advance.
