HELP!!! Yeast infection during pregnancy

I’m 14 weeks and 5 days and tonight I’m noticing I have a yeast infection! It came out of no where and I have no idea what I’m allowed to take since I’m pregnant....I do have a tablet of fluconazole but I’m not sure if that’s off limits now that I’m pregnant... also it’ll take two days before my doctor replies back to message and I’m so itchy down there it’s unbearable. WHAT CAN I DO? 😩 PLEASE HELP
