Hi mum, I also had slightly higher amniotic fluid towards third trimester before and I remember feeling quite worried after the scan too. From what I was told, an AFI of around 19 is usually on the higher side of normal or borderline depending on the clinic range, so it doesn’t automatically mean danger, but it does mean they will monitor you more closely. If your doctor already asked you to cut down sweets and rice, I think it’s mainly to help control blood sugar because that can sometimes affect fluid levels. I wouldn’t say you must avoid everything sweet completely, but just be more strict and moderate, and follow your gynae advice closely since they know your full case best.
