Hi! So just been for my 20 week scan, all measurements were spot on but his tummy was measuring bigger. I am being sent for a rescan in two weeks time. According to online, this happens because the mother has diabetes or thyroid problems, my tests have come back fine. Does anyone know of any other reasons? Just a big baby? Measured wrong? Growth spurt? What happens if the babies tummy continues to measure bigger. Has anyone had similar experience? TIA
