How To Heal Vaginal Area From Itching ?

I dont know if i have a yeast infection or not. My clitoris and basically everywhere around my vagina is extremely itchy. My discharge is whitish. and can be clumpy. It smells wierd. I have started getting bumps that look like pimples on my labia major. Also i have a couple bumps on my labia minor as well. It hurts to pee after i itch. Ive had one sexual partner which was 8 months ago. What is this? and what can i do to make it better?
