USS today - 5w3d

Em

Ok - hi. So this is my second baby / my older daughter is 12 in July.

I just wanted to double check thoughts.

My bHCG at 4w4d was 3500 - is that normal?

Had scan today and measured 5w3d and no heartbeat - could see flicker but couldn’t get a reading of it.

I was expecting to be 5w6d so I guess this is all within the realm of normal?
