Fluconazole (diflucan) during second trimester

I’m 21 weeks and I’m noticing another yeast infection coming on. I just cured one last month with some cheap OTC seven day cream but I forgot to ask my doctor for more today and to top it off I don’t have enough $ until Friday to by more. I have an extra Fluconazole I’m wondering if that’s okay to take? I’ve googled it and got mixed answers, anyone else takin this during pregnancy?
