Megan hunny,

I think you did a blast trf didn't you? These usually have a lower hcg than most pregnancies because of the lateness of the implantation. My level at 13dpo was 73, which was considered relatively high for a blast trf, believe it or not. I had another BT done 3 days later, and it had gone up to 260+. That was when the coordinating nurse reminded me that you can't tell by one hcg reading how things are going. What you need to see is if your levels are doubling every 48 hours.

If you like, hun, PM me your levels and dpo, and let me have a look. I also have a reference website that shows hcg levels for IVF (taking into account age of embryos) that you may like to have a squizz at.
