Ay, mama, I understand your worry, but please get this checked with your OB as soon as possible, okay? Even if baby is still moving and heartbeat is there, any change in movement pattern kailangan i-monitor ng doctor, lalo na at 27 weeks ka na. A few of us mums have been through this and honestly, the peace of mind from a quick check-up is so worth it, hindi rin mahaba ang ultrasound. Your instinct matters, so trust it and don't wait.
