What Causes Thick White Vaginal Discharge With Odor?

Hi, my name is Anna Mork and I have a question.. I've been noticing that I have a foul smell down in my girl area, some white-ish chunky dischard and some minimal itching... I have no idea what's wrong and I'm scared to talk to a doctor about it... I'm not sexually active either.. Please let me know if u can help
