Sayang, lower abdominal pain at 35 weeks with difficulty lifting your left leg, please see your doctor or go to the clinic/hospital as soon as possible, ya. This needs proper checking sebab ada banyak things it could be, and doctor boleh do an examination to make sure baby okay. Don't worry too much first, tapi jangan delay juga. Better safe than sorry at this stage of pregnancy. Let me know how it goes, okay?
