I am currently at the doctor and I had an ultrasound, I am 33+4 and my baby boy is weighing 4 lbs and only measuring in the 15th percentile. I am a FTM and I don't really knows what this means for my baby. the baby has been diagnosed with a congenital heart defect, coarctation of the aortic arch with bicuspid vavle and dilated right ventricle, and he will require heart surgery at birth but I have been told many times that he has to be big enough for surgery. I don't know what to think....
