Ah mama, totally normal yan lalo na kasi first time mo! With anterior placenta, the flutters can be mas inconsistent kasi naka-cushion ng placenta ang movements, so some days you'll feel them more, some days hindi pa, mga kaibigan ko with anterior placenta din nag-complain ng ganyan. Baby's probably moving all the time, pero hindi mo lang ma-feel consistently, especially when you're busy or distracted. As long as you feel movements regularly (hindi kailangang every hour, ha), you're good, pero if you're still worried, no harm asking your OB about it during your next checkup, okay?
