yeast infection while pregnant...

i tested positive for group b strep.... my doctor put me on ampicillin now im getting a yeast infection i hate taking antibiotics for this exact reason!! Anyhow how did you treat your yeast infection while pregnant the nurse tool two days to respond to my message about this and suggested a 7 day dose of monistat. ugh i havent done monistat in so long but i remember feeling like it was leaking out of me. Not really something you want to deal with at work. And for 7 days?!? i need relief now! Any andvice is greatly appreciated!
