Hmm, honestly yan ay medyo early pa para makita ang grade 2 placenta, kaya I'd really suggest checking with your OB about that, sometimes it depends sa ultrasound equipment or kung paano nag-measure, pero better safe than sorry talaga especially sa ganitong early stage ng pregnancy. A few of my mum friends had similar findings and their doctors just monitored closely, so walang instant panic pero definitely worth asking your doctor kung normal ba for your specific case at if kailangan ng follow-up ultrasounds!
