8 1/2 Week Ultrasound

Went in for my initial appointment today and had a vaginal ultrasound. The doc measured the size of the baby at only about 6 1/2 weeks instead of 8 1/2, which according to the date of my last period I should be. We didn’t hear a heartbeat, and now I am needing to do hcg level blood testing. Has this happened to anyone? I haven’t experienced any miscarriage symptoms.
