My Vagina Is Very Itchy,when I Use The Restroom My

My vagina is very itchy,when i use the restroom my urine has a very bright color. I was sexually active before this happend. It hurts around the entrance when i try to have sex. That went away now i have discharge and sometimes it has an unpleasant odor. I havent gotten my period for 2 months. I wake up nauseous when i wake up. Ive been feeling like that for a week now.
