Yeast infection that won’t go away!!

I’ve been having yeast infections my entire pregnancy (29 weeks) I did the one hour gestational diabetes test last week and failed got a 159. Im thinking it was the gum I was chewing that morning. (I know stupid move) everytime Im nervous I always chew gum, I wasn’t thinking straight that morning 😅 anyways I thought I didn’t pass because the gum. But I’ve been having a really bad yeast infection these past few days and nothing is working. Im supposed to go tommorow for the 3 hours test and im starting to feel like im not going to pass it. I know recurring yeast infections is one of the symptoms of gestational diabetes.
