This afternoon we received our first beta number. A beta blood test measured the amount of pregnancy hormone (hCG) in your blood.
Our number was awesome: 385! The nurse commented that, because I had two follicles, twins are a definite possibility with a number that high. But there's no way to know until the ultrasound. And, of course, we will be ecstatic either way.
The first beta number doesn't tell you much. It is the comparison between 2 blood tests that determine whether the pregnancy is looking good so far. My next beta is Monday, and we want the number to be at least double at that time.
