Alah normal je sayang, heart rate memang akan naik during pregnancy sebab body kita kena pump more blood untuk baby! A few of us complained about this to our doctors and they said it's completely expected, some mums even felt palpitations here and there, macam jantung nak keluar. But if it's making you dizzy, breathless sangat, or you're worried, best check with your doctor lah, especially nearer to delivery. Relax ja, your body tau apa dia buat.
