Ultrasound

Hey ladies so I had an sudden ultrasound appointment today as my doctor said I am measuring 3 weeks behind. Baby measured great currently she is weighing 6lbs 9oz, is measuring at 37 weeks and 4 days a week ahead, and is head down and in position.😁 Is it common for an ultrasound technician to ask if you are having contractions when you get an ultrasound this far along? She was very vague when responding probably because she isnt supposed to say anything. She asked if I am having contractions and how soon I am seeing my doctor. I've been having more frequent and painful Braxton hicks I've no idea if that shows in an ultrasound. Any tips or info is greatly appreciated
