It's Official, I'm 4 weeks pregnant!

My beta hcg level was 69.8 yesterday. I go in tomorrow morning to have it checked again. It should be somewhere between 110 and 140 if things are going well. The hcg number doubles every 2-3 days in early pregnancy, even with multiples. (It's just higher to start with when there are multiples.) Based on the averages that I've seen on the web, I think I just have one embryo that implanted, but we'll know in a week or three.
