High hcg but empty gestational sac

Patient

Q: LMP 1/7 had positive urine preg test 2/11 + beta hcg = 32000. 2/12 US showed empty sac - should I be concerned? Is this normal? I go back for repeat US 2/18 but am concerned if they will see yolk/fetal pole. Such high hcg should have shown something

Symptoms:  No pain or bleeding
Doctor

A:   Hi,
Thanks for the query.
I understand your concern.

According to your last menstrual period, the gestational age by 2/11 will be 36 days or 5 weeks 1 day.
Usually, Ultrasound can detect fetal pole with heart rate after six completed weeks of gestation.
Generally in singleton pregnancy beta hcg levels at 5 weeks 1 day can range between 1,200-1,800 mIU/ml. But multiple gestations like in twin pregnancy, at this gestational age high beta HCG levels can be expected like around 2,400-36,000 mIU/ml.
Another rare possibility is a molar pregnancy.
To come to one conclusion please go for repeat ultrasound after 1 to 2 weeks as advised by your doctor, possibly by the time yolk sac with fetal pole can be detected.
Hope this helps.
Take care.
