Weight Gain Doubts

so my OBGYN said I should gain only 8-10 kilos (17 - 22 pounds), thats the recommendation they now give women, I had a BMI of 21.4 and a Waist to Hip ratio of .75 pre pregnancy, but according to her I was chubby to begin with, did anyone in a healthy weight range also got this recommendation? I was aiming to gain around 12-14 kgs ( 26-30 pounds)

I am now at 27 weeks and have gained 8 kilos (17 pounds) from the start.

most of the weight has been the belly and breasts with hardly any overall.
