Aah normal je sayang, pregnancy hormones memang boleh buat macam tu, penat siang tapi malam tak boleh tidur! A few of my mum friends cerita the same thing masa pregnant, it's frustrating betul. Try napping earlier in the afternoon if boleh (like 2-3pm) so tak terlalu lama sebelum tidur malam, and maybe stick to a bedtime routine yang consistent; I found warm milk or a short walk membantu jugak. Kalau insomnia ni jadi really bad or you're worried about the fatigue itself, best check in with your doctor just to make sure everything's okay, they might suggest something safe for pregnancy.
