Hoping for the best, yet preparing for the worst

I had my final beta test today, and my HCG levels came back lower than they would have liked. My previous number was 5533, and my number today was 7203. They would have liked a 50 to 60% increase, and I fell about 1000 short of that. They are bringing me in early for an ultrasound. My appointment is scheduled for 8:45am tomorrow. The RE says that sometimes such high initial numbers means that more than one embryo implanted. If that happened, one of them might be lagging behind and might not make it, which could explain the less than perfect increase in my numbers. That would be a nice scenario, as one embryo could still possibly be ok. The other scenario would be that we could lose the entire pregnancy again. All we can do is wait and see what tomorrow brings. Continue to keep us in your thoughts and prayers....every little bit helps.
