Aww, congratulations, mama! I totally get the nervousness, first time kasi talaga ang scariest! But honestly, ang best person to explain ang ultrasound results is your OB mismo, kaya make sure to ask her lahat ng questions mo during your next visit, ha. A few of us mums always write down what we want to ask kaya hindi natin makalimutan! You've got this, and I'm sure everything's okay, just let your doctor give you that peace of mind. Sending you lots of healthy baby vibes!
