Its been confirmed that im not pregnant by two blood tests. im still showing all the symptoms, including nausea, fatigue, food aversions and cravings, and now a sore breast and cramps. im not stressed. what could be happening if not pregnancy?

Pseudocyesis: If a pregnancy has been ruled out, it is important to rule out any hormones disbalance that could be causing those symptoms. I recommend you to visit a endocrinologist. Also there is a very rare condition called pseudocyesis or psychological pregnancy in which women get all the symptoms including the growth of the abdomen, but they're not pregnant.
