Am I Hungry?

Sorry if this is a dumb question but ive had gastritis mostly all my life. In case u dont know what that is its all your insides are swollen and comes with horrible heart burn and pain. I just knew to eat when all my insides started burning . Well since i got pregnant ive been eating better and now i wake up with my stomach growling it doesnt stop and my insides feel like if theyre hurting. Ita grrrrr super loud it even wakes me up this has been happening for days. So igs i forgot the feeling of being hungry which is why im asking if this is what being hungey feels like?
