Since I work for a blood lab I had always decided that I would get my blood drawn just for our own amusement. I am glad that I did. It gave us all a little peace of mind too! The day I got a positive pregnancy stick I got my first beta done to check my HCG levels. They generally have you do it every two days to make sure that the number is doubling like it needs to be. If it isn't then it can mean all sorts of things.
On Thursday my first beta came back and it was a 13. That means that the hormone level at 13 can be detected on a First Response pregnancy test and on a cheap dollar store one.
On Saturday I got my results back and they were 27.40 which means they at least doubled! We were excited that things were looking good so far. We are aware that anything can happen since it is so early at this point in the pregnancy.
