Uy, first-time mom worries, totally get it! But honestly, this is something you really need to clarify with your OB directly, every pregnancy timeline is slightly different, and only your doctor can explain what that means for your baby specifically. A few of us mums have had similar notes on our ultrasound reports, and what seemed worrisome turned out to be just how things were measured that day, but I'm not a doctor, so don't rely on what I say, ha!
Schedule a follow-up appointment if you haven't na, or call your clinic para ma-explain nila properly, wag mag-stress alone, okay?
