Hi mama! Congrats on your baby girl! Pero ang best person to explain ang ultrasound results mo is talaga ang iyong OB, siya ang makakaintindi ng lahat ng technical details at makakasiguro na lahat ay okay with your pregnancy at baby. I'd recommend making a follow-up appointment agad if you haven't discussed it in detail with her, kasi iba-iba ang readings at important na malinaw ang lahat for your peace of mind. One of my mum friends dini-document niya lahat ng tanong before her OB visits para ma-address lahat. You got this, and your doctor is the best resource for these things!
