6 week ultrasound

Lu

So I have booked in to have an early ultrasound because I’m so anxious about everything. It’s on the 31st when according to my LMP I would be like 7 + 5 but I actually think i’ll only be 6 + 2 because I ovulated later. Are they likely to be able to see anything? I’m unsure because I’ve seen some people on here being able to see something and have a heartbeat but then some people say it’s a waste time because it’s unlikely that they will see anything... and just wanted opinions really. I don’t want to go and them not be able to see anything and waste my money and for it to fill me with even more anxiety...
