For those of you who aren't familiar with this stuff let me explain:
As I am an older mom they are concerned with my chances for chromosomal abnormalities in the fetus (the older your eggs are the more degraded they can be).
Here is the chart all the sights are so keen on

Now, keep in mind early screening generally focuses on Trisomy 21, more commonly known as Down's Syndrome. We aren't worried about Down's, in my experience in life extra chromosome=extra awesome. What does concern us are the other trisomies which are "incompatible with life"
The question then becomes what do you do if the initial screening comes back positive for one of the trisomies? You have options of other tests. They all do however pose a threat, however minor to the fetus. So, when you have already been informed that your pregnancy is pseudo high risk (because of your age and what can come of that fact alone) you aren't willing to take too many other chances.
The two main tests, both of which are pretty invasive (from the Bean's perspective):
CVS (Chorionic Villus Sampling): Where they take a sample from where the placenta meets the uterine wall.
This is done between the 10th and 13th week of pregnancy. (Why is that important, because it is before the major risk of miscarriage has past. And while the odds of miscarriage are only 1 in 100 but since my chances of conceiving naturally were about 52% I don't listen to odds too much) Some studies have also shown a link between CVS and babies born with missing fingerprints or toes, not a big deal but why do it if it isn't absolutely necessary?

Amniocentesis: I think most people are familiar with this one BIG freakin' needle through the abdomen (guided by ultrasound of course) to obtain amniotic fluid from the placenta. So...they have been doing this one for decades, why worry....because it is no safer today then it was 20 years ago. There is still increased risk of uterine infection, miscarriage, leaking amniotic fluid, and Rh sensitization (which may or may not be a factor for us.) And that doesn't even take into account if your little one is a squirmer, while the chances of for serious needle injury are rare they do still exist.
So we have decided that we will not proceed beyond the quad screening which will be done at about 16-18 weeks. We are only doing that one because there is no risk to the Bean and it will put the midwife's mind at ease.
So while I understand some people's desire to know ahead of time etc...It doesn't really matter to us. Bean has so much to teach us regardless of how any test comes out, so yeah I won't risk the health of my baby or pregnancy on a test, which isn't foolproof anyway.
Ciao for now~
