Hindi lang yan direct sign na gising ang baby, mama! Your heart rate can go up for so many reasons, stress, caffeine, activity, hormones, kaya hindi automatic na nag-reflect ito sa baby's state. That said, kung nag-worry ka na mas mabilis na talaga ang heartbeat mo lately or parang unusual, mas better na i-mention mo sa OB mo sa next check-up para ma-monitor properly, lalo na kung may accompanying dizziness or shortness of breath.
