It was the winter that I had spent bleeding, attuned to no particular rhythm. Sometimes my period would come on twice in one month, or last for four weeks instead of one. Or, in between spells of bleeding, I would find rust-colored specks in my underwear, or else what seemed like rivers of blood, dark and sticky as blackberry jam. Mostly, it hurt only a little, a pain I could store in the back of my mind and ignore. Sometimes when I was on my feet all day I would feel woozy and cold, and when I went home at night I’d lie awake for a long time, wondering as I turned from my back to my stomach whether there was some position that might keep me from waking up with blood staining my sheets, like a marriage bed visited by an incubus. I took iron supplements. Eventually, I went to a doctor.
