Can anyone tell me their similar situation and outcome?

I had my LMP July 18

I ovulated August 1

I got a faint positive pregnancy test on August 11 (10DPO)

I was 6w0d as of yesterday August 29

At my early US we saw a 6week sac, yolk sac, and fetal pole all measuring good but didn’t see the HB.

I had bloodwork done yesterday as well and they gave me my numbers today which were:

HCG: 19,000 (rounded up slightly)

Progesterone: 17.5

Why didn’t I see the HB?! I’m so sad I feel doubtful and anxious. I have to wait the whole long weekend to go back on Tuesday to make sure it’s there. How will I keep sane?? 😢😢😢
