Hi dear and thanks for your query. Greenish vaginal discharges aren t normal but they tell that you may have an infection. The most common cause of green vaginal discharge is a sexually transmitted infection known as trichomoniasis. The discharge often has a foul odor and is typically more yellowish-green than pure green. Intercourse and urination may cause discomfort, and the genital area may be itchy. Pelvic pain may also occur but is not common. Hence get a vaginal swab done to rule out this infection. All the best
