No idea... that is just what he told me last visit I saw him. I was CD30 last time, he asked me whether I felt pregnant, I said no. He told me to wait til a week after my period was due (going off that the one before was 33 days). But the next day after my appointment AF arrived, so it was only a 30 day cycle. I ovulated the same day on both cycles too, so that really stumped me why there would be a 3 day difference in the length of my cycle. Back to see him in 2 days...
