Sabar je mama, it's actually quite common during pregnancy, kencing kotor boleh happen sebab hormones dan kidney function changes, so scanning is the right call to make sure everything okay aje. A few of my mum friends went through the same thing and it turned out fine, doc just wanted to rule out infection or any issues with the kidneys lah, and after that confirm semua normal je, the scan process itself is straightforward and takde pain, just like ultrasound. I know the worry is real, tapi betul-betul relax aa, this is standard precaution especially during pregnancy. Usah overthink, just go for the scan, get the results, and then you'll feel so much better once doc says all clear!
