Baby's stomach not visible on scan

Nastja

Hello. Today I had a scan and everything was fine except it was the second time in two weeks that they could not see the baby's stomach on the scan. Has anyone had a similar experience? Did everything turn out OK? The doctor said that it could be because he just emptied his stomach and peed, due to less fluid it could influence the size and visibility of the stomach. I'm feeling really worried. Any reinsurance?
