And...

prego

Sometimes a picture is worth a whole lotta words. We're preggo. My Beta Blood test results came back...and came back strong. My hCG levels were a 150-160 count, which is great. They were hoping for a 40 level, so not bad for 8dp6dt (that's "8 days past 6-day embryo transfer). Now we want it to double by the next blood test on Thursday.

But for now, its YAY-TIME! We're both very happy-- we're cautious b/c there is still much more our Little B (Bs?) need to do--but we're very thrilled to get back results like this.

SOME FUN FACTS ABOUT hCG & IVF (i.e. stuff I never knew before we started this whole quest)
Human chorionic gonadotropin (hCG) is a hormone produced during pregnancy by the placenta. It starts to be produced shortly after an embryo implants, and is expected to double approximately every 48 to 72 hours in early pregnancy. The absolute level of hCG in a pregnant woman's blood is less critical than the rate of rise. A failure to double properly reflects slow placental growth, which is very frequently associated with abnormal embryonic development.
While hCG levels are expected to double in early pregnancy, the rate of rise generally slows as the level increases.
It's not possible to determine whether you're having twins or a singleton by hCG levels alone. The range of normal values for twin gestations fall squarely within the range of normal values for singletons. It has not been proven that multiple gestations have faster doubling rates than singleton pregnancies.

No matter how many stories with a positive outcome you've heard about slow-rising hCG levels — "15% of normal pregnancies have an abnormal rise!" — and no matter how many times you've heard that once you see a heartbeat you're practically in the clear — "The miscarriage rate drops to 3%!" — hCG levels that don't rise properly are a troubling sign even in pregnancies where a heartbeat is established.
IVF pregnancies generally have
lower hCG levels than other pregnancies. The theory is that non-IVF pregnancies implant sooner, thereby having more time to generate hCG than a transferred embryo would. (Special thanks to "Turns Out You can be a Little Pregnant" for collecting this info)
