"Hysterical" pregnancy

I know it's an outdated term, but is false pregnancy a thing anymore?  I mean, does anyone know someone who's had it?  I'm asking because I'm two weeks late but frer is consistently coming back negative.  Any chance I've convinced myself I'm pregnant?   (For those who are wondering: so-called "hysterical" or "false" pregnancy is where the woman psychologically believes she's pregs and then starts to show signs of pregnancy like nausea and Breast tenderness even though she's negative).
