Measuring about five days ahead???

Natasha

Had my first ultrasound a week and a half ago was supposed to be 6w4d based on my lmp which I’m sure of because I always track it. But based on the ultrasound I measured 7w2d she didn’t seem concerned but even if they are here they’d send a report to my doctor who is on vacation for two months :( with my precious pregnancies I was always a day or two behind never ahead. Do you think this is normal? We saw the heartbeat which she showed me but didn’t tell me the bpm but I didn’t ask either. Thanks for any input
