My wife was scanned and here result are as follows;

1. uterus is bulky and habours a single gestational sac with no fetal node echo
2. GSD - 31mm
3. GA - 8 weeks + 4 days
4. cervical Os is a bit dilated
Asssesment of early cyosis

What does the above information mean?

I believe the person to ask is your wife's Physician who knows her age, physical condition, other factors.
