Insanely hungry!!

Ok so I’m a ftm and of course I don’t know what to expect. I’m 14 weeks and insanely hungry. When I say this I am not over exaggerating or being dramatic. I have to eat every 2-3 hours sometimes I can go a LITTLE longer but rarely.. is this even normal? I get really sick if I let myself get to hungry. Before I got pregnant I use to go a long time without eating another meal so I’m not use to eating this much. I understand that I’m feeding for two but will the hunger ever get better? or does it stay this way til birth? If so I will definitely be fat ..
