My beta HCG value was 15,049 (!). That seems really high compared to the ranges I've been looking at! Though ome of the ranges I've looked at said the high end is around 7,000 for 5 weeks, so I guess it makes sense that it's doubled again since I'm a couple days past 5 weeks. No wonder I'm already getting the hook effect!
I'm really hoping it's not from twins - I don't think we could handle that!
But in general it's awesome news! With my first loss, my HCG was 24 at 5w3d (obviously a sign of miscarriage), so I'm at least really happy that it's high.
