Vaginitis signs and symptoms can include: 
Change in color, odor or amount of discharge from your vagina
Vaginal itching or irritation
Pain during sex
Painful urination
Light vaginal bleeding or spotting
 If you have vaginal discharge, the characteristics of the discharge might indicate the type of vaginitis you have. Examples include: 
Bacterial vaginosis. You might develop a grayish-white, foul-smelling discharge. The odor, often described as a fishy odor, might be more obvious after sex.
Yeast infection. The main symptom is itching, but you might have a thick white discharge that resembles cottage cheese.
Trichomoniasis. An infection called trichomoniasis (trik-o-moe-NIE-uh-sis) can cause a greenish-yellow, sometimes frothy discharge.
