Empty sac?

Sierra

So I went to er on the 3rd they didn’t see anything on the ultrasound as my levels were only 34 I went and had another ultrasound done on the 12th and they seen a sac only.... I was measuring 5 weeks 1 day I went back yesterday a whole week later and still didn’t see a fetal pole measuring 5 weeks and 4 days I’m not bleeding or cramping I’m just hoping this is a good outcome my last period was may 2nd but I have cycles anywhere from 28 to 34 days so hopefully it’s just early I’m so scared
