How big is your baby weighing at 29/30 weeks?

Well when I went to the doctor she had told me that I was measuring too big she said he was normal but his size was just a little big for for gestational time.

She assumed that I had diabetes but my test came back negative the only other two causes could be my uterine fibroid or the fact that his dad is 6-3.

Has anyone had this issue or dealt with this? What could it be and could he be coming early? Everyone says I look like I'm carrying twins but I'm only 29 weeks and 4 days. Excuse my clothes
