Help!! Tmi

So I thought I might of had a yeast infection so I used monistat extra strength monday. I had heavy creamy white discharge and today Wednesday 2days later its not clumpy discharge like cottage cheese no burning or itching I would have thought the yeast infection would b gone by now but it seems to be worse maybe? I never used monistat before and thought that's the way to go other than the doctor I have an apt on the 14th and will let him know then but I'm just worried. Any advice or has anyone used this before I'm confused and hope it isn't worse?
