Sabar ya, detail scan findings mmg kadang ada surprises tapi tak semua itu serious, banyak babies recover atau it resolves on its own je by the time they're born. One of my mum friends had something similar at 23 weeks and by the repeat scan at 32 weeks everything was fine, alhamdulillah. Definitely follow up dengan doctor untuk more scans (usually they monitor closely), tanya dia exactly what it means and what the next steps are, sebab condition to condition lain mak. Jangan stress dulu, doctors tau apa yang mereka tengok, and at 23 weeks there's still time. Hang in there!
