Yes. There are several reasons that this can happen: 1. A condition called "ectopic pregnancy" when an egg becomes lodged within a fallopian tube. A sonogram can determine this. 2. A condition called "hysterical pregnancy" when a woman might want to be pregnant but whose body is just mimicing the condition. Sometimes this happens when menopause occurs. You might laugh about this one: 3. Sometimes, if your male, you can feel sympathetic symptoms for a female that mimic pregnancy. Hope this helps!
