Big baby

So I had an ultrasound on Monday and they said she was between 7-8 lbs...but then the dr told me that they count get an accurate measurement because she is so far down and she's guessing she is closer to 9 lbs...I still have 3 weeks left...I hope they just say they want to induce me next week...wishful thinking...I'm considered full term since I'm 37+1...I don't know if I should try to induce it myself or just wait to talk to my dr...FYI I had to see a diff dr cuz mine was out on a family emergency and they do things differently...
