I don't know, but I have the same problem. When you find out, let me know...
Hydrogen peroxide can be effective at removing blood stains from sheets, including period blood stains. It works by breaking down the proteins in the blood that cause the stain. It's important to spot-test a small area first and wash the sheets immediately after applying hydrogen peroxide.
Yes, sometimes women can cause this by their own discharge, or, just before or after their periods. Even if the sheets are washed the stain can be hard to get rid of. I wouldn't get too excited or worried over it.
I read on one website that the food and water we consume has a varying level of acid in it, if the food we eat has a high level of acid, then our sweat and bodily fluids can actually cause a discoloring stain depending on the dye in our sheets.(acid in the skin reacts with the dye).
The most common cause of ceiling stains is water leakage or seepage from the roof or plumbing pipes.
I'd have described them as more of a yellowish-orange, myself. Ninhydrin reacts with amino acids. Amino acids are all over your skin. With most of them it forms a yellowish compound; with a couple it's more of the blue-purple you're describing.
