Life is filled with mysteries, some trivial and others impactful. One mystery that often puzzles people involves their undergarments, specifically when something unusual appears. For instance, noticing what seems like bleach spots on underwear can be unsettling, especially when the cause is unclear.Many women may feel embarrassed to ask about this, but the Internet often has the answers. One common theory is that these mysterious marks come from vaginal secretions. Dr. Vanessa MacKay of the Royal College of Obstetricians and Gynaecologists explains that the vagina naturally cleans itself through secretions and contains protective bacteria.

The pH level of the vagina is mildly acidic, usually around five or lower, which is healthy and normal. This acidity, along with natural discharge, can sometimes affect the fabric of underwear, leading to discoloration. While this is a common occurrence, disrupting the balance with products can result in infections.In short, the Internet can provide the answers we seek, as long as we know where to search.
