You may have wondered what that lighter patch is that appears on your underwear, or the underwear of someone with whom you are close enough to be rifling through their pants.

It's not a sign of dirtiness or bad hygiene to have paler patches in your pants, it's something which happens when the acidity of a perfectly healthy vagina spends time in contact with fabric, and it's particularly noticeable on darker fabrics.

Having a (moderately) acidic vagina is protective against unhealthy bacterial and yeast infections. Your pH level will differ over your lifetime, normally at around 3.8-4.5 pH in the years you are menstruating, and slightly above that before puberty and after menopause.

This discharge increases during ovulation and pregnancy due to an increase in cervical mucus.

So, you don't have to panic about the lighter patches or overwash your underwear.
