when can they start seeing a baby on Ultrasound

I'm sorrY I don't bring good news. With a transvaginal ultrasound you can see a baby and heart beat at 7 weeks. I had spotting at 10 weeks they did a transabdomjnal ultrasound (with a full bladder) and we were able to see a baby with arms legs a hb. Chances are at this point u should have seen something there is of course always the chance their equipment is obsolete and they missed it. At 11 and 12 weeks is usually when they do the nucual fold triple screen tests and at that point the baby looks like a little person. Are
they doing further testing or another U/s ? I'm so sorry you're going through this I hope this was just a mistake and u end up with a healthy baby
