Q: What is an imaginary pregnancy (pseudocyesis)?
A: What you are describing is called 'pseudocyesis' or 'pseudopregnancy.' Pseudopregnancy is a false pregnancy when a woman has many signs and symptoms of an actual pregnancy, such as missed period, nausea, breast tenderness, or even an enlarged abdomen. Some even think they feel the baby move.
With a pseudopregnancy, pregnancy tests are repeatedly negative and there is no pregnancy found on ultrasound.
