Yeast Infection

Okay guys I have a horrendous yeast infection. Worst I’ve ever had in my life. I’m 13.5 weeks and my doctor prescribed one pill of fluconazole and a cream to be used like monistat. My pharmacy didn’t have the cream ready tonight and now my doctors office is closed. Would it be a bad thing to do a treatment with monistat tonight for some relief and then hit it tomorrow with the prescription cream when it comes in? Or do I suffer another night without?
