Ohhh I feel you! Sakit pinggang dengan keletihan tu memang draining lah. One thing someone in my mum group swore by is making sure your iron levels okay, kekurangan darah memang boleh buat you rasa super lemah and exhausted all the time, so check with your doctor pasal tu. Pair it with vitamin C-rich foods (oranges, strawberries, tomatoes) sebab it helps your body absorb the iron better. Besides that, rest la as much as you can, tapi jangan lah terlalu baring je, light stretching or a short walk pun boleh help with the back pain and actually boost energy a bit, even though it feels counterintuitive. Stay hydrated juga, sometimes thirst masquerades as tiredness. If it's really bad, mention the sakit pinggang to your gynae, they might suggest a maternity support belt, which quite a few mums find game-changing for comfort and energy levels!
