24 weeks (1 baby)

Wah, this needs a proper check with your doctor or specialist, sayang, kidney swelling in babies can be benign hydronephrosis (which resolves on its own) atau something that needs monitoring, tapi only your scan results dan expert opinion boleh confirm. Since you're at 24 weeks, I'd suggest request a follow-up scan maybe at 32-34 weeks to see if it improves, and talk to your OB about what the measurements actually show, a few of my mum friends went through similar scares and everything turned out fine, but it's best to have that reassurance from your doctor directly rather than guessing online. Jangan worry too much for now, okay? These things are picked up early for a reason, and most cases resolve beautifully. All the best, mama!
