If you gave us an idea of where you came across “P&S,” I think we could be of more help. 🙂

Just a thought – If you only heard “P&S,” any chance it’s actually PMS that you mean? That’s premenstrual syndrome, and all you ever wanted to know about it can be found at www.wikpedia.com (just type in “PMS”). Hope this helps.
