My vg is itchy and feels irritated, no pain, no burning sens no white discharg washing myself with bottled water and seems helping can it be a yeast?

Yeast is possible: I asume VG means vagina, right? Many women don't understand that yeast often causes no vaginal discharge. The main symptoms are itching and irritation, without discharge. In other words, it sounds like you have pretty typical symptoms. See your doctor for professional diagnosis. Or you could try an OTC yeast treatment -- but for sure see your doctor it that doesn't clear things up in a few days.
