Oo, totally normal! Even though second trimester is supposed to be the "energy trimester," maraming kaibigan ko na nag-complain pa rin ng antok lalo na towards the later weeks ng second trimester like you. Ang katawan mo talaga busy making a human, so kahit wala nang morning sickness, the fatigue can stick around or even come back. Try mo lang mag-nap kung pwede, stay hydrated, at pagkuha ng iron-rich foods, a few of us noticed tumaas ang energy namin ng slight once nag-up kami ng iron intake. Pero if sobrang grabe na parang abnormal, best to check with your OB na lang para peace of mind! You're doing great, mommy!
