Aiyooo, 8 weeks and morning sickness hits hardest masa ni! Memang ramai mums around me dulu complain the worst is around weeks 6-12, so you're in the thick of it sekarang. Few things yang helped my friends, eating small frequent meals (even just crackers), staying hydrated, and resting as much as possible lah. Tapi since you're feeling exhausted like that, better check in with your doctor or midwife to make sure everything's okay and get some proper support, they might suggest B6 supplements or other things that help. Hang in there mama, this phase will pass, I promise!
