What were your Hcg levels at 5 weeks?!

I don’t know the date of my last period but based on when I think it is I would be around 5 weeks on Tuesday when I had a blood draw. They did an ultrasound and only saw a black dot on the screen that looked like an empty gestational sack. They said that is normal and I go back in 2 weeks for a repeat. My levels Tuesday were 601 and I’m waiting to hear back what they were yesterday. So I’m curious what everyone else’s levels were because 601 seems low to me and the woman on the phone was acting weird so they’ve got me paranoid.
