I'm sure it is. From what I understand, stress can delay ovulation, which in turn, lengthens your cycle due to the luteal phase being on average 14 days or so. Correct me if I'm wrong ladies... Anyway, my sister had a 41 day cycle one time during tax season... She's an accountant. So I think stress can definitely play a roll.
BTW, I still have no period yet, and tomorrow it will be 37 days for me. Definitely not pregnant, however (had to do an HCG test before my surgery). I just got off the pill last month so I suppose my cycles are going to be weird for a while.
