Your chart looks inconclusive to me, but if it helps any I had horrid, erratic periods whenever I wasn't on the Pill and settled down to 42ish day cycles when I came off the Pill: the cycle before I conceived was a 56-day cycle with LOADS of pg symptoms, the cycle I did fall pg was slightly shorter and gave me no conclusive pg symptoms at all! Good luck for either being pg or getting pg in the very near future.
