Brief Answer:
It is abnormal.

Detailed Answer:
Hi,

I can understand your concerns.

Sonography should show heart beat of fetus by 8 weeks.

The fact that it did not show heart beat even by 12 weeks is abnormal.

It points towards fetal death but please get it confirmed by a repeat doppler today and serum beta HCG .

Thank you.

Sonography show the heart beat of fetus from first test.

But the Doppler did not show.

Is there any particular time/weeks to do a Doppler test?

Brief Answer:
Repeat scan

Detailed Answer:
Dear,

Ideally doppler is more accurate than plain sonographies.

Its very strange as dopplers pick up heart beats earlier.

So please repeat a sonography as i think there is an error in reporting
