Sakit pinggang dan bawah perut memang common lepas czer, terutama kalau ada scar tissue dari first pregnancy, a few of us czer mums experienced yang sama, some kuat lagi the second time around. But sakit yang kuat over 2 bulan tu kena check with your gynae, boleh jadi ada issues dengan scar or just posture/core yang weak, better safe dapat proper assessment. Jangan risau sangat dulu, just make sure you get it checked out okay? Take care!
