6w4d ultrasound

We had our first ultrasound today & drove an hour just to be told it’s too early to see anything but they want us back in 6 days. I thought for sure they should’ve been able to see. She seemed like she rushed the whole process. Will they see anything when I’m 7weeks 3days ? Or will that also be too early ? I can’t keep taking off work every week when I’ve asked to just wait til I was 8 weeks.
