I'm going to be 36 weeks on Sunday, my baby is measuring 40 weeks already. I had an appointment today, and my dr won't even check an ultrasound weight because she says she will not take him before my scheduled c-section at 39 weeks. I've never carried a baby that long due to size, I've only gone 38. I don't feel like she's listening to me at all! Is it too late to get a different dr?
