Sayang, I know this feels scary especially as a first-time mum, but please don't worry alone, go see your OB-GYN or paediatrician soon to talk through what the sonographer found, okay? They can explain it properly and what it means for baby. A few of my mum friends have had similar scan findings that turned out fine, but some needed follow-up checks, and that's exactly why the sonographer wants baby seen after birth. It's just being careful, not necessarily something serious. Once you see the specialist, you'll feel so much better having answers instead of guessing. Hang in there, mama, you're doing the right thing by getting checked.
