probably. unless he had a great machine, he might not pick it up. The h/b is supposed to start at a little over 5 weeks, something like 23 or 25 days past conception. But not all u/s machines are created equal. Some are much better then others.
My DR found my baby's at 6w2d. I thought for sure it would be too soon. But his machine is also used for Level II ultrasounds so I think it is pretty good.
Also you might be a day or two off in your EDD and that can make a difference too.
