I was on depo for a decade or so before chemical menopause, thus no periods, & I've never kept tampons on hand for friends. My BFFs always seem to be on the rag when they visit (coincidence? something I bring out in them? dunno), & the random ancient maxipads I carelessly have in the back of a drawer are fine if they happen to not carry their own. IME, gals BYO if it's that time of the month!
