Totally normal lah! Second trimester ni hormones naik turun, badan kau busy supporting pregnancy, memang akan rasa penat. A few of my mum friends said the same thing, especially yang kena kerja or manage household sendiri. The fact that you perk up sikit when suami ada probably means you need emotional support plus the extra hands, which is completely fair. Suggest you chat with your doctor to check if you're anaemic or anything, sebab sometimes pregnancy fatigue boleh jadi sign of something yang boleh di-manage dengan supplements.
