Aiyo I feel you, that's the strangest feeling kan, rasa hungry tapi tak mau makan, so frustrating! At 6 weeks the hormones are really messing with your head, a few of us went through this phase and honestly small frequent meals helped more than trying to force down proper meals, like a few crackers, a smoothie, atau some fruit every couple hours instead of waiting to feel properly hungry. Makan apa yang boleh masuk je for now, and remember this phase usually passes by second trimester, but if you're really struggling to keep anything down do check with your doctor.
