Sakit ngilu-ngilu tu normal je at that stage, but the dizziness when you wake up and can't even stand properly, definitely worth checking with your doctor, babe, especially if it's happening regularly, sebab boleh jadi low blood pressure or anaemia la. Istirahat yang cukup, minum air banyak-banyak, dan jangan bangun tiba-tiba from lying down, try sitting up dulu for a moment before standing. You're doing great, first-time mama anxiety is real but getting checked will give you peace of mind!
