Infections and remedies?

Chelsea • I am 30 years old and have been dealing with PCOS my whole life.
Im 7+3 and found out through all my parental tests that I have a UTI. My OB prescribed antibiotics to treat that and now I've got a yeast infection. Can't get in to see a dr for a few weeks. Does anyone know if it's safer to take over the counter remedies while pregnant?
