Guys. Let's dispense with delicacy here. You know how there are certain times of the month when the little lady is, shall we say, slightly grumpier and puffier than usual? Do you remember the last time she threw a (full) coffee cup at you when you commented that it must be "that time of the month"? Do you live in dread of that hormonally-charged temper every four weeks? Well, never again live in fear of not knowing when your sweet Dr. Jekyll turns to Mrs. Hyde. Be informed. Now you can have her cycle delivered to you right along with your favorite blog feeds. Never again make the mistake of blaming an argument on PMS when it's truly because you SCREWED UP!
