He's referring to the Fetal Pole which is the early stage of the baby's spinal column. They can be hard to see for some women on early sonograms, and the test has to be repeated at a later date. They should have a better indication of what's going on next week. Many women have posted on here of similar situations with not seeing the fetal pole on the firs sonogram, but seeing it on the second, so I hope that is the same for you.
Wishing you the best!
Thanks for responding. I guess I will find out for sure on Tuesday when I see my ob
Not sure if maybe he said the fetal pole that's wht they see in there with the yolk sack and stuff :) depending on how far you are it may be to early though.
