Monistat question.. Please help me

So I had a yeast infection and took the two oral pills my doctor had given me in case the antibiotics caused me a few problems. However after the six days that it was supposed to take to work, I still had a few slight symptoms. So I bough the one day Monistat. It all fell out about an hour and half after inserting and burn quite a bit after, and is getting slightly better. I was just wondering if this was normal or if something is wrong down there? Please help.
