I'm a SAHM since my 2nd pregnancy. Yes it is normal to feel that way. My 2nd pregnancy I can be hungry every hr and it doesn't matter at anytime. But, I don't follow the growling and hunger to avoid indigestion or unnecessary stomach pain. So ill eat in small portion but ensuring I'm full, snacks in between when I'm hungry again and after 8/9 no food that's heavy except fruits or biscuit or bread.
