We met with the Genetic Counselor this week and it was very informative. It seem that only one of the three things they consider for the first trimester screening was abnormal.
My
HCG was normal, the baby's
nuchal fold was normal, it was only the
papp-A which was abnormal coming back lower than average. Which is why my risk for a child with down syndrome rose from my age related risk of 1 in 215 to 1 in 131.
Yes, this is still less than one percent and the risk of the
amnio is anywhere from 1 in 300 to 1 in 1000 depending on which study you refer to.
So hubby and I have decided not to have the
amnio because we worked too hard to get to this point in a pregnancy and would not be able to live with ourselves if we lost the pregnancy due to the test. We are going to proceed with the second trimester screening in a few weeks and then have the detailed anatomy scan at 19 weeks. The Genetic counselor said if this scan come back clean for any soft markers then my risk will be
recalculated and lessened.
On another note though the decreased
papp-A value has been linked to other pregnancy
complications, such as placental
insufficiency, fetal death, preterm birth,
IUGR, low birth weight and
preclampsia. So the Dr has decided she will monitor me more closely with monthly ultrasound with focus on the placenta. Especially since my mother lost three pregnancies between 18 and 24 weeks.
So for now we are just letting it all go with God, whatever will be will be. It is out of our control. Until the baby is viable, even if there is a problem with the placenta, nothing can really be done. So I cannot stress over something that is beyond human control.
