Good to know, brother. Apparently her Googling took her to obscure websites claiming the opposite, citing a hadith about irregularities in this function being the "work of Shaitan", and also that "Shaitan runs through the veins like blood". She says that the only reason she wondered about any connection in the first place was that emotional stress etc. has never had a noticeable physical impact on her before. I will be happy to pass on your opinion that the claims of the obscure websites were misguiding.
