Fluconazole yeast infection

I’m 14 weeks 1 day pregnant. I have a slight yeast infection due to taking antibiotics for a uti. My obgyn prescribed me Fluconazole 150 mg, take one today and another in 4 days. Has anyone taken this while pregnant because everywhere I’m reading says it’s not safe to take during pregnancy. I have a list of approved medicines from my doctor and I can also take Monistat 7 so I’m thinking about just taking that instead. I’m just really weird about taking medicine especially now that I’m pregnant
