What causes false pregnancy?

At this time, there’s no answer to why some women experience pseudocyesis. But there are three leading theories. Some mental health professionals believe it’s related to an intense desire or fear of becoming pregnant. It’s possible that this affects the endocrine system, which in turn causes symptoms of pregnancy.

Another theory relates to wish fulfillment. Some mental health professionals believe that when a woman yearns to be pregnant, possibly after experiencing multiple miscarriages, infertility, or because she wants to get married, she may misinterpret certain changes in her body as a clear sign that she’s pregnant.
