Aww mama, sakit pinggang in first trimester boleh jadi sebab hormones sudah mulai relax ligaments, and your body is shifting already lagi pun kalau dulu third trimester baru sakit, this pregnancy memang lain-lain je timing nya, some mommies start earlier. Kena try posture yang baik, jangan berdiri terlalu lama, and consider pairing with antenatal support belt boleh membantu, tapi since it's quite bad, do check with your doctor or midwife to make sure semua okay first, ye? Hang in there mama, you'll get through this
