5 weeks and 5 days but no gestational sac on ultrasound

Miccs

This is my first pregnancy. I had a positive home pregnancy test and had my first consult to my ob- gyn earlier, ultrasound was done but gestational sac is not yet visible and was told that maybe it was too early. I was advised to have quantitative pregnancy test done (beta hcg) and still awaiting result. What are your thoughts on this?
