Welcome to the ehealthforum and I am glad to help you out.

Your concern is regarding your abdominal girth at 34 weeks gestation. For fetuses at 36-40 weeks' gestation, the cut-off for predicting intrauterine growth retardation (IUGR) was an abdominal circumference measurement that was less than 31 cm. So 37 inches abdominal girth is absolutely normal at 34 weeks gestation.

Moreover, abdominal girth holds value when the abdominal girth is more than the period of gestation as it may indicate polyhydroamnios or multiple gestation. Normally we take abdominal girth to be 2 inches less than the period of gestation as a normal limit. So there is nothing wrong with your abdominal girth. You can rule out IUGR by regular ultrasound examinations.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For an exact diagnosis, you are advised to consult your doctor. I sincerely hope that helps. Take care.
