Everything you need to know about vaginal pH balance

Did you know your vaginal pH balance plays a major role in your overall intimate health? When this delicate balance is disrupted, you might notice itching, irritation, or unusual odor - all signs that your vagina’s microbiome may be out of sync. Whether it’s bacterial vaginosis, a yeast infection, or just a temporary imbalance, understanding your vaginal pH is key to keeping things fresh, healthy, and happy.

Let’s break it down.

What is vaginal pH?

pH measures how acidic or alkaline something is, on a scale from 0 to 14:

pH 7 = neutral
Below 7 = acidic
Above 7 = alkaline

Your vagina thrives in a moderately acidic environment, which helps protect against harmful bacteria and infections.

What is a normal vaginal pH?

A healthy vaginal pH typically ranges between 3.8 and 4.5. This acidity supports the growth of Lactobacillus - the good bacteria that produce lactic acid and keep bad bacteria in check.

Your pH can fluctuate naturally due to:

Menstrual cycle changes;
Hormonal shifts;
Semen (pH 7.1–8.0);
Antibiotics;
Tampons, lubricants, and synthetic products.

If your pH rises above 4.5, it can lead to symptoms like abnormal discharge, itching, or a fishy odor often linked to BV or yeast infections.

The “bleaching” effect of vaginal discharge

Yes, it’s real and totally normal. Vaginal discharge contains acidic compounds that can discolor underwear when exposed to air. This is a sign of a healthy vagina doing its job: cleansing itself and maintaining balance. Pretty magical, right?

How do you know if your vaginal pH is off?

Common disruptors include:

Period blood – raises vaginal pH;
Semen – alkaline, can disrupt balance;
Antibiotics – wipe out good bacteria;
Douching – damages microbiome;
Scented products – irritate and imbalance.

Symptoms of imbalance:

Itching or burning;
Unusual discharge;
Fishy or sour odor.

Note: These symptoms don’t always mean a pH issue, consult your GP if they persist.

Can you test your vaginal pH?

Your vagina is a self-regulating superstar and most of the time, it doesn’t need help - just respect. Routine testing isn’t necessary unless you’re experiencing symptoms. There are at-home pH test kits, but they can’t diagnose the root cause. For accurate results and treatment, visit your OB/GYN or healthcare provider.
