Many women at times perceive their vaginal discharge as an abnormal discharge at some point in their lives. But commonly seen as a normal physiological discharge. This is a white or clear discharge that varies all throughout the menstrual cycle.

It’s always sane to avoid than to find a cure after getting ill. As with all STIs, the only way to prevent STIs is to abstain from sex. Lower the risk by using condoms correctly every time you have sex.

Vaginal discharge colour shades


With no symptoms, if the vaginal discharge is white or yellow in shade then it is a sign of healthy lubrication. But if the white discharge has a viscosity like cottage cheese or is accompanied by a strong odour, it can indicate an infection.


If you are having a red or a pink discharge around the time that you’re expecting your period then this could just be completely normal. It means that there is blood around and that’s what’s causing the red and the pink colour of the discharge. Towards the end of the period, a lot of women find that the discharge becomes more kind of like a dark brownie colour. This is because the flow of the blood is so slow and the blood stays much longer it gives a brown or dark red tinge to the vaginal discharge. This is nothing to worry about.


If the discharge has a very slight yellow hue, it may not mean a problem. This is especially likely with a change in diet or dietary supplements.

Discharge that is a darker shade of yellow, yellowish-green, or green usually signals a bacterial or STI. Almost all the infection shows yellowish-green vaginal discharge. So beware and consult your doctor as soon as possible.


Another time, when you can get a pink discharge or a red discharge is shortly after sex, within the first 24 hours, can be due to the fact that during sex there’s friction. So you can have tiny cuts and scrapes in the vagina which bleed and then cause the vaginal discharge to be like a pinky or reddish colour.

Sometimes some women experience a pinky discharge or red discharge or just blood in between their periods, in medical terms, it is called intermenstrual bleeding (bleeding in between your periods). It is a sign that you need to go and see your doctor.

Another example is if you have entered menopause. So if you’re a woman who hasn’t had a period for like a year or close on a year and then suddenly you start getting vaginal discharge that’s pink or tinged with red even if it’s not bleeding then that is a worrying sign. Because it could be a sign of endometrial cancer. Consult your doctor soon.


Vaginal discharge can be considered as the mirror of vaginal health. So keep an eye on the appearance, viscosity and odour of vaginal discharge. Consult your doctor in case of any significant change in either of the parameters.
