Yeast Infection Affect on Baby?

I went to the doctor probably a month ago & they said I had "a little bit of yeast". Sent a prescription for the infection to the pharmacy and sent me home. Well, two weeks later, the pharmacy had lost my prescription so my doctor sent over a new one. And now it's been a week and the pharmacy keeps saying they have ordered the cream and will have it "tomorrow by 2". I've went back everyday at 2 and been told the same thing. They're closed tomorrow and I don't get paid until Monday. What affect could this have on my baby? I'm 31 weeks. Monday if they still don't have it, is there something over the counter I can buy?? Help please 😭😭
