Ahhh I feel you lah, tunggu doktor memang penat especially when you're hungry and sleepy! Saya pun ingat masa pregnant anak ketiga dulu, energy macam habis je, kena makan snacks dalam bag selalu. Pukul 17 minggu dah, so you're in the thick of it, try munch something light before appointments, like biscuits or banana, helps dengan the grogginess. A few of us mums swear by keeping a bottle of isotonic drink in the bag too, membantu jugak. Jaga yourself ya, pregnancy anak ketiga memang lain sikit
