yes, you can see the heartbeat on an ultrasound.
Unfortunately not likely - it should detect the heartbeat by then
Typically after five weeks an ultrasound can detect pregnancy. Although you may not be able to see the heartbeat, you may see a thickening of the uterine lining that indicates pregnancy.
A vaginal ultrasound could possibly detect an audible heartbeat at 4 weeks, which would be six weeks since your LMP.
i would say no
It depends on the way it was tested. If using a hand-held machine sometimes the heartbeat cannot be found at 8 weeks. If the doctor was using an ultrasound machine a heartbeat should be visible at 8 weeks. The doppler, which most doctors use to detect a fetal heartbeat, can usually not detedt the heart until around 10 weeks, especially if the woman is overweight. As stated above, the ultrasound can detect it sooner.
It is quite common, particularly if it is before about 10 weeks, but it can also show that the baby has died
It's not likely. The ultrasound might not even be able to detect a heartbeat yet. If you do see anything at all, it will be more like a little tiny dot!
can listen for the fetal heartbeat with a stethoscope, use Doppler ultrasound to detect the heartbeat, or give the mother an electronic fetal nonstress test. In this test, the mother lies on her back with electronic monitors attached to her abdomen.
Yes, it is possible at least sometimes to see the defect during an ultrasound.
what if ultrasound doesn't detect a fetus at 5 to 6 weeks?
