Hi. I m a healthy 46 year old, married, Caucasian woman. Lately, I ve been getting light pink stains in my panties. No, it s not blood. It is a deep fluorescent pink that doesn t change color as it dries. When I take them off, there s a smallish stain. If I leave them in the laundry pile for a couple days, the stain spreads and stains other clothes.... I can t find any reference to this condition anywhere.
