Yeast infection? Please help!

So i’ve had this discharge and think its a yeast infection because of its consistency.

So I took Canesten thrush 3 day and just finished but nothing seems to have changed in my discharge. There was a period of 2 weeks where it was itchy asf but it stopped and also it can smell a little sour sometimes, sorry gross! Its more the smell that annoys me as it isnt itchy and doesnt burn at all but the smell is just sour!

Any help is appreciated thanks! (i also dont use scented soaps or eat like terribly bad)
