I saw the baby and heartbeat at 6w4d on one of my pregnancies so around this time. Hope that helps
the heart starts beating at about 5.5 weeks.
by the 5th or 6th week, depending on the sensitivity of the ultrasound machine, whether it's a vaginal or abdominal ultrasound and, well, to be blunt, how "plump" you are
You can usually "see" the heartbeat by the 6th week or so, but you won't be able to "hear" it on a doppler until week 10 usually, or later.
THANKS FOR YOUR REPLYS :)
