Very similar for me hun. I waited another 2 weeks but in my case there was a baby but no heart beat or growth. Please don't lose faith it's upsetting and heartbreaking but it will happen. I have by body time to heal and fell pregnant again 4 months later x x x bug hugs
Same thing happened to me i had to wait another 3 weeks and it ended up been a blinded ovum which is a sac with no baby i had a natural miscarriage at 10 weeks.
That's still pretty early. Don't worry and wait a couple more weeks for your next US
