The results of the 2nd transfer are in; the surrogate (J) is pregnant, with the beta being 191.5 mIU/mL on the 15th day of embryonic life.
I did a happy dance (which mostly involved hyperventilation) till I realized that is a low value; my first 2 pregnancies were around 450 mIU/mL at this point, while my 3rd pregnancy (the trisomy) was in this range, being around 140 mIU/mL.
Some trisomies tend to have lower beta values, while others (like trisomy 21) can present with higher values.
I'm trying to think of everything possible to explain this; I'm tiny (I weigh just over a 100 pounds), while J could easily be twice my size, which means she has a much higher blood volume as well, which means a same amount of hormone produced is getting diluted in a much larger volume of blood----yeah---that is what I'm going to go with. I'm so not clutching at straws, right?
The good news is this is not likely to be a twin pregnancy, which is great if it actually continues.
Off we go again; pregnancy #4 is underway.
