3 weeks 4 days with my 2nd pregnancy

Aiyoh, yes lah! Hormone surges start very early in pregnancy, so massive hunger at 3 weeks is totally normal, a few of us experienced it before the positive test even came. Your body is working overtime, jadi memang lapar je. Just eat when you're hungry (healthy snacks help lah) and listen to your body, especially since you already know the signs from your first pregnancy!
