Rest assure that it's normal. Your LMP may not be 100% accurate. Ultrasounds can detect how far along you are. You are still pretty early that's why you were told to come back 2 weeks later. I thought I was 11 wks going to 12 but after I did the vs, I found out I was only 10w4d pregnant. I was told to come back 1 week later for the nuchal translucency scan.
