Stress can certainly affect conception. This happens because stress affects the function of the hypothalamus (the gland in the brain that regulates appetite, emotions, and hormones).
It is important to distinguish between chronic stress and stress caused by a sudden event. Sudden stress—such as a death in the family, an accident, or a divorce—can disrupt your cycle and interfere with ovulation.
Of course, this varies from woman to woman. Some women find that even traveling abroad can delay ovulating. Others report that a serious traumatic event did not affect their cycle at all.
It is also important to remember that stress is not always a reaction to something negative. Brides often report irregular cycles because they are stressed about preparing for their wedding.
The good news is that delayed ovulation simply lengthens your entire cycle. It does not shorten the luteal phase—which usually lasts 12 to 16 days after ovulation. So while stress can affect when you ovulate, it does not reduce your chances of achieving a successful pregnancy.
