Aww sayang, I haven't personally gone through that, but a few of my mum friends have had slightly thicker fluid measurements at NT scan and everything turned out fine, baby was completely normal lah. Tapi honestly, this is one of those things kena discuss properly with your doctor or specialist, because they need to explain what "cecair agak tebal" means in context of your baby's other markers and your age lah. Don't worry too much first, sebab NT scan is just a screening tool, bukan diagnosis, many times it's just how baby is positioned or measurement variation je. Minta them to explain clearly and if needed ask for second opinion, that's what I always tell myself when nervous about scan results!
