Eh normal je tu, sis, kadang-kadang first trimester memang rasa mual sangat sampai tak larat nak makan, so berat boleh turun sikit. A few of us experienced the same thing, especially masa morning sickness mencapai puncak. Tapi lepas first trimester biasanya appetite balik normal and berat akan naik balik, so jangan worry sangat. That said, kalau drop berat tu agak drastis atau ada symptoms lain yang weird, better check with your doctor just to be sure everything's okay with baby. Mana bulan you sekarang?
