Think of your v&ginal pH as your internal microbial ecosystem warning signal.
When things are balanced, pH sits in an acidic range, usually between 3.8 and 4.5, thanks to your good bacteria (mainly Lactobacillus).
These microbes make lactic acid and hydrogen peroxide, and keep the environment calm, moderated and unfriendly to troublemakers.
If your pH rises above 4.5 and stays there, it can signal a bacterial imbalance (dysbiosis).
Bacteria are the regulators of pH, when protective species drop, opportunistic species increase e.g.Gardnerella.
This usually accompanies a change to discharge, odour and comfort overall as the dominant bacteria produce their own metabolites and less effective acids.
A pH that’s in range but accompanied by thick, white, clumpy discharge or itch often points toward yeast overgrowth (Candida).
Fungal microbes can and do thrive when bacteria are imbalanced but in recurrent forms of thrush we see symptoms even when the bacterial environment is stable.
A single elevated reading might just reflect natural variation, maybe after s3x, new lube, or around ovulation.
But a consistently high pH (over several days or cycles) means your microbial community may need support.
That’s why tracking over time is key, you’re watching for trends and patterns and associations with activities, hormones and health.
During ovulation, estrogen rises and mucus production increases.
You might notice a slight, temporary rise in pH, this is normal and healthy in the absence of symptoms.
It helps sp3rm survive the journey.
We usually don’t track during menstruation, as blood temporarily raises pH and skews readings.
pH testing and tracking is a cost-effective, simple way to keep an eye on your internal environment.
It can help you spot shifts early, before symptoms appear, and understand how hormones, lifestyle, and treatment are shaping your v&ginal ecology. This means tou can act sooner and often prevent symptom flares.
Your v&ginal pH is feedback from your ecosystem.
