Baby's weight at 32 weeks

So, I wanna know what everyone else's doctor/Midwife estimated their baby's weight to be around 32 weeks....I've read so many things saying that baby should be 3.8 lbs or more by this point (for 50th percentile) and my doctor said mine is measuring just under or right at 3 lbs. I'm not sure if I should be concerned that he is smaller?

Funny thing is my husband was born at 9lbs 6oz and his mom and brother were similar....I've bee afraid of having large baby this whole pregnancy 😂
