Hi Ladies, so I'm currently 29 weeks and 6 days pregnant. Yay!!

So we just had a ultrasound for baby. The sonographer doing my scan said that I have more fluid then usual around baby. She also said that baby was average weight and but he is shorter then average.
She said that everything else seems normal and that he is very active. Also saying that an active baby is a healthy baby.
Just wondering if anyone else has had baby measure shorter than average and whether it is a common thing?
