Yeast Infection Help.?

So I have or had a yeast infection, my dr. prescribed me diflucan wih 1 refill. I took it tues night and it is fri morning. Basically the symptoms are pretty much gone, the itch is kinda there but not really. My question is should the itch be there at all or is it normal. I dont really have the money to get the refill but if I should get it I will. If anyone has experience with diflucan and how long it takes for the symptoms to be 100% gone please share. Thank you!
