Yeast Infection while Pregnant :(.....HELP!!!!?

I'm currently 5 months pregnant with my second child (Girl) and I've have a yeast infection for the first time and had it for 3 weeks now. I've tried everything . I've been using wipes, creams and used 3 boxes of Monistat 3 day after I used the meds my doctor gave me. I need HLP and please don’t say see my doctor, thanks.
