Measuring Big

Patient: Hi my name is Alexis. I am almost 34 weeks pregnant with a baby boy and I have been consistently measuring 2-3 weeks bigger at all my appointments since about 19 weeks. I am starting to get nervous that he is going to be too big and my doctor keeps blowing it off like its no big deal. I don’t know how I can get her to understand my concerns or if it is possible for them to induce me earlier or perform a c section. At my last appointment he was measuring at 37 weeks and I do have a smaller framed body. Luckily I was seeing my doctors nurse practitioner who scheduled a ultra sound for a week from today. Should I be worried or what should I do?
