Yeast infection

So I just found out I'm about 5 weeks pregnant and currently battling a yeast infection that just won't go away. My gyno gave me a prescription for an internal suppository to use at night which helps with the itching and discomfort but as soon as I pee and take a shower In the morning the itching and discomfort returns. What can I use during the day for the itching on the outside of the vagina?
