Sakit pingang sebelah kiri masa hamil tu memang biasa, especially at 35 weeks bila baby dah besar dan berat, banyak mum friends saya komplen pasal ni juga! Tapi sebab it can sometimes indicate something yang needs checking (like kidney issues or positioning), better jaga-jaga and mention it to your doctor or midwife, especially if it's getting worse or ada symptoms lain macam demam atau susah kencing.
