Oo normal yan sa pregnancy, mama! Ang heart rate natin talagang tumataas kasi ng extra blood volume at hormones, pero if parang sobrang bilis o may kasama pang severe nausea at dizziness, better check with your OB lang para peace of mind, a few of us din nag-worry noon at nalabas fine lang, pero mas okay kung confirmed na ng doctor. Anyway, make sure ka nagpapahinga ng maayos at nag-hydrate well, kasi dehydration din nagpapataas ng palpitations na talagang nakaka-anxious.
