Uy, mama, that's such an important question, please check with your OB or ultrasound tech about that heartbeat reading, okay? They're the ones na makakasiguro kung normal yan sa exact timing ng baby mo.
I know it's nerve-wracking waiting for confirmation, but don't worry yourself too much until you hear from the doctor, most of the time, everything's perfectly fine! Let us know how it goes, ha? Sending you baby dust!
