yeast infection

Hi Girls, so recently i found out i have a yeast infection. Today i went to the store and bought Monistat which is a "cure" that looks like a oval type ball, i bought the 3 day supply. Today was my first day and i inserted it and everything was fine. A little later i went to the bathroom to take care of business (lol) and i realized the ball slid out but its smaller than a penny so im guessing it has been dissolved more than half its size because its normal size is about the size of a quail egg. Is it possible the entire process was ruined and have to start over or should i just continue the process? Please Help, Thanks!
