6 week ultrasound gone wrong.

I literally just had the most unsettling US experience. I went in for the heart beat and dating and literally came out with no info. Absolutely none. They showed me the sac. That was it. But then used the wording “usually they have you come back in 1-2 weeks when there is an actually baby to measure.” WHAT IN THE ACTUAL FUCK. what kind of wording is that to an expectant mom who recently suffered a miscarriage? I had the US at a different hospital than my OB because I was closer to this one and now I’m regretting the whole process. My doc said she would look and give me a call to tell me what they actually did but she think I had super bad, or super inexperienced techs. Anyone else have this happen and everything be just fine??
