Sayang, abdominal pain in early pregnancy boleh jadi normal, tapi since you've had a miscarriage before, please call your doctor or go to the clinic/hospital today, don't wait. Better to get checked and have peace of mind than worry at home. A few of us mums have been through similar scares, and honestly, it's always better to get a professional assessment, especially at your stage. Doakan semuanya okay!
