Aiii sakit perut camtu memang menyusahkan lah, first mom! Boleh jadi constipation, or maybe your body is adjusting post-pregnancy, a few of my mum friends went through the same thing after giving birth, especially kalau tak minum air cukup or tak exercise lagi. Better check with your doctor or nurse para tengok apa yang happening, sebab sometimes it's just dehydration or diet-related, tapi kena make sure aje! In the meantime, minum banyak air and try adding some fiber dalam diet, tapi if it persists, jangan tahan, go see your GP okay?
