Thanks for your query.
At 8 weeks, the fetus should measure about 1. 6 cm.
Hence, I do not see anything to worry about in your case.
Pubergen and Corion are injections given for pregnancy
Based on your details, i can see no indication for these.
If you are a recurrent aborter, or have threatened abortion
, or some ominous finding in your ultrasound
is there, then these can be prescribed.
You need to clarify exact details of the ultrasound report and your clinical findings for better judgment.
Till then trust your obstetrician and comply with the advice
