Yeast infection :(

Brittany
After three days of 2000mg of penicillin I have landed myself a nasty little yeast infection and still have 4 more days of antibiotics to take :( doctors office is closed on Thursdays and they are calling for 8 inches of snow tonight where I live so more than likely will be closed tomorrow . Anyone know any safe for pregnancy over the counter  meds or home remidies I can try until I can get ahold of the dr ?
