Slmt mlm! Sakit perut and memulas at 23 weeks boleh jadi normal contraction (Braxton Hicks), but since you're having both perut and punggung pain together, please call your doctor atau pergi clinic/hospital sekarang to check, better safe daripada sorry lah, especially at this stage. Don't wait, okay? Your healthcare provider kena check you properly just to make sure everything okay with baby and you. Take care!
