I am only 4 weeks pregnant with my first, so very early, but I am finding that I have the need to eat constantly. For example for breakfast, cereal just isnt enough, I need cereal and toast. At lunch I ate my normal meal which would fill me up, but at the moment it's just not. Dinner time, I can have my meal and feel full, then within half an hour my stomach is going. I am trying to subside the hunger with healthy snacks but finding it hard. Is this normal or am I just being pigish?
