Empty sac?

Amanda

5 weeks 3 days today... I was woken up this morning by BAD period-like cramps. All weekend I had spotting so this terrified me. Obgyn clinic didn’t have any availabilities so I went to the ER. My HCG was 16,384 and an abdominal ultrasound showed a sac. The sac appeared to be empty tho and they didn’t see a heartbeat or anything. Anyways, the doctor said I didn’t miscarry and everything looks good but is an empty looking sac normal at 5 weeks?
