YEAST INFECTION? or something else

My vagina has been itching and burning for the past week and I assumed it was a yeast infection because I get them sometime so I havent taken any medicine. Yesterday my perineum was really sore, irritated and was bleeding when I wipe and I'm having heavy creamy non stick discharge and having cramps. Could this all be a yeast infection? or something more? please help i'm not very educated on things like this.
