Distinct empty stomach feeling

Has anyone had that really distinct empty stomach pregnancy feeling and no matter how much you eat you’re starving and not been pregnant? Idk how else to explain it besides just feeling like your stomach is hollow and I’m almost hungrier after eating lol.. anyways I had that pretty much my whole pregnancy with my son. I just finished my period so im sure I not pregnant but it’s just such a weird and distinct feeling. Has anyone had that feeling and not been pregnant?
