mensuration menstruation

I don't think you'd know what I'm about to say,
           but I'd still like to hear you try.

Sometimes the Lord visits me in the night
        and asks me to bleed a little more.
            If I can, I will—and I do,
                                            for a day.

    The next night, the Lord might ask
that I give a little more, so I do, do it again,
    and pour out the blood on the ground— 

                     Again and again.

Pour out libations for the homegirls no longer around.

     Till the Lord comes around again 

                                           next month.

And asks me to bleed a little more.
