A fetal heartbeat should be seen, and the gestational sac should also be visualized at 6 weeks of pregnancy. The fetal pole is usually seen as well, which is the first thing to develop in a viable pregnancy.
You should be able to see the baby (though it will look more like a blob). You may be able to see the heart beat as well. The yolk sac may still be seen, or you may see the start of the placenta. You should be able to see the fetal pole too.
At six weeks gestation you should be able to see a fetal pole, gestational sac and heartbeat of your baby or babies. This will vary depending on where you are in the week as well.
Most likely at 6 weeks you will see a black oval (your uterus) and inside a teeny tiny bean attached to a yolk sac. You may be able to see arm and leg buds on the little bean unless your EDD is off. You may also be able to see the heart beating
In most cases the technician was able to see the baby and heartbeat on a vaginal ultrasound scan at 6 weeks. The baby looks like a little tadpole. In some other cases this may not seen. That is it takes some more time.
