I totally believe this. I don't have this experience, in particular. With myself, when I lose track of my cycle, I often notice right away just from the scent of my lady parts. LOL. It's like honey and nectar mixed together. Makes me totally drunk on myself. LMAO.

I can smell diabetes, though. Sometimes. Especially Type I. Smells like stone fruits that are just starting to go rotten. Again, not bad...just different. I just need to be within 3 feet of a person to notice.
