I had the test with the first, didn't have GD bub 4.5 kg but not chubby just crazy long

Second time around similar advice as your mw gave u

She said I was very low risk and based on ds1 being big and not a gf bub and straight forward birth not to bother

She also said that it's a pretty subjective and questionable test anyway and that if I did choose to ha e I should sneak out and exercise between the Bts because " of you have GD a little walk wont make it gp away"
