Blood work, nervous.

Breanne
So I had blood work done yesterday. I ovulated on the 9th of November, they called back and told me that my levels where low but they where a 10. I am unclear of the scale. I know that anything over a 5 is considered positive, but could the number go down or will it go up. I'm pregnant but I'm afraid that it will "disappear." I have to go back in tomorrow to do more blood work. I'm nervous.
