Green vaginal discharge is considered abnormal discharge.
As soon as you notice green discharge, especially if it is frothy, clumpy, or mucus-like and has a bad odor, contact your doctor.
It may be a sign of a sexually transmitted infection or an infection called bacterial vaginosis. 22 Jan 2019

Bacterial vaginosis
Bacterial vaginosis (BV) is an infection caused by an imbalance in “good†and “bad†bacteria in the vagina. BV is not an STI, and often the cause of the infection is Gardnerella vaginitis.
Factors that may increase the risk of developing BV include having a new sexual partner, having multiple sexual partners, douching, smoking, and having a general lack of “good†bacteria.
Common symptoms of bacterial vaginosis include:
Vaginal itching
No inflammation
Thin, white discharge
Burning during urination
Grey, yellow, or green vaginal discharge
Foul-smelling “fishy†vaginal odor.
