Question

If you fear you are going to have a big baby due to genetics hubby was a 13lb 24in baby and I was an 8.1lb 20inch baby so I am worried this one will be huge and I do not want to c section. What do I tell me dr? I talked to a dr the other day (wasn't my dr) sometimes in this office they throw you to different Drs if your low risk for just normal check ups but what do I ask my dr at my next appointment. This one dr talked about doing a scan will they do it if I have concerns? I have been measuring ahead but not gaining much weight I'm 34+ weeks and I have only gained 6 lbs and I keep measuring 1-2 weeks ahead. Would my insurance cover it if the dr request it? What should I do?
