Uy mama, that's a bit technical kaya mas better na itanong mo talaga sa OB mo directly para ma-explain niya properly, ultrasound findings can be tricky to understand without the full context of your case! A few of us mums usually ask our doctors to break it down para clear kami, kaya wag mahiya to ask agad agad. At 37 weeks, sigurado na makikita mo siya soon pa lang, so best na discussion na yan sa appointment mo mismo. Ingat na lang always, at sabi namin dito ay always better to clarify with your doctor para walang worry!
