Dizziness tu memang common dalam early pregnancy sebab hormones dan blood volume changes, tapi combined dengan rapid weight gain baru 5 weeks, better check with your doctor to rule out anything like anemia atau blood sugar issues, a few of us had dizziness yang turned out kena iron-deficient, senang je nak address once you know. Don't overthink the weight yet lah, berat badan starting point mu different from first pregnancy so comparison tak equal, plus early pregnancy bloating boleh jadi culprit, bukan actual gain. Makanan-wise, focus on nutrient-dense stuff, nasi + protein (ayam, telur, fish), leafy greens, oats, bukan restrict calories sebab you need extra nutrition anyway. Just see your doc soon untuk the dizziness bit, dapat peace of mind and proper guidance untuk pregnancy ni.
