Vaginal discharge (TMI) {No Pictures}

So for the last few days I've noticed a creamy white/yellowish discharge and the inside of my vagina feels very irritated and it bothers me to walk or even sit and I sometimes get this burning feeling in it.. Anyone know what this could be?

P.S. I did call my doctor but she can't see me til the 15th and there's no way I can wait that long..
