I've just had my 31 weeks antenatal, and GP found trace of glucose in urine - not enough to be worried about, but he's getting me in again next week to check. Gestational Diabetes is the concern. One symptom is needing to urinate more, and i have noticed that I do lately, but then again I guess that's a normal symptom of pregnancy! I need to go pretty much an hour after every glass or mug of fluid I drink, but I don't wake up in the night to pee… He also said the test showed I was dehydrated today, tho, and that might explain the glucose.
