In that area (and that area only) I am blessed: the only thing I notice from my period/cycle is the bleeding (duh) and that I need to pee more often during my period.

Can you schedule your work so that you can take the morning off? Maybe if you stay an hour longer 4 times a week, you can take the morning off on the 5th day? (Doesn't even have to be the same week if you prefer not to lengthen your days the other days of the week you're PMSing)
