I have had on and off vaginal itching for about 2 months now, either on my labia or at my entrance, last month assuming it was a yeast infection I bought a 3 day Canesten pack and it cleared up but just the other day almost a month apart the itching kind of came back its just once in a while and not that bad, I'm having a white or yellowish sticky thick discharge that I can like scoop out it sticks to my walls. What could this me? Another yeast infection? Bacterial infection? An STI?
