Just seeking some reurance after early ultrasound?

Yes :) just relax, it was probably too early to detect anything. The tech was probably more mad at whoever ordered the early scan more than anything, she probably just knew that she wouldn't see anything and was wasting time... Even though that's not your fault and she should have treated you better! I went to the ER at 5w1d (due to heavy bleeding) and they did a tummy and transl scan. The scan (which I also never got to see) did not show much but they did see a tiny sac in there, but couldn't get heartbeat yet. Right now your baby is developing SO rapidly that even just a few days makes a HUGE difference in what they can see. I went in again a week later and they could see a sac, a tiny baby inside, a strong heartbeat, and even a second sac they had not seen the first time around! So don't stress...your little bubba is in there growing up a storm, safe and sound :)
