Did they say what the number is? It's good to consider both outcomes, but you really shouldn't make a diagnosis from one beta. It matters if it is rising/ doubling. According to my WTE book, Week 5 can range anywhere from 18 to 7000something! And even then, just because you don't fall into that range (above or below) doesn't necessarily indicate that you won't have a healthy pregnancy. I hope your beta comes back with good news tomorrow! We are here for you either way
