6 week ultrasound

Ta

I have an ultrasound scheduled for Friday but I’ll only be about 6 weeks. It’s not a medical but it’s an entertainment type of US. I know I won’t be able to see much but the only thing I’m really looking for is a heartbeat. Is 5weeks6days - 6weeks too early to see a heartbeat using trans abdominal ultrasound? Thinking I should reschedule for later
