Beta is in and.....

I'm pregnant! I'm in total shock I was so sure it was going to be negative! My beta is 24, which I think is low, but she said it's still very early. This is also why the hpt's came out negative. I'm trying to be cautiously optimistic, but I am also so scared I have been down this road before. I want this to be the one, and only positive thoughts from here on in. I go back Friday to make sure my levels are going up so I'll feel better then.
