Can stress delay ovulation?

[threepiecesuite]

Due AF yesterday but no sign of her yet. Have POAS tonight but bfn.
Lots of cramps, wind and nausea.

AF never been so much as an hour late in 3 years of ttc #2. Every 27 days to the hour.
My question is - around ov time, just before Xmas, we had lots of stress (a close bereavement and other things), could the stress have delayed ovulation? Hence a delayed period? Or even caused ovulation to skip entirely and I won't get a period at all?
Has anyone experienced this?

Yes, stress can definitely delay ov. Has happened to me twice over the past 18 months, ironically both times when I was getting really stressed about not conceiving...
