15 weeks : ))
15 weeks and nothing to report. All is smooth and fine. No scan this week so above pic will have to do. Bubble should measure around 4 inches.
We have our triple marker test next week. Double marker at 12 weeks wasn't done as it's widely regarded as unreliable and only causes anxiety. Tell me about it! We had that done last time and the results were horrible, showing a very high incidence of trisomy 18 - Edwards Syndrome. At any rate, they used the wrong age of our donor, 21 instead of 28, so it would have been even worse. What a horrific time - we spent an agonising four days gearing our brains around having a disabled child, that most likely would die in the womb or be stillborn. Though we lost baby, it was not because of trisomy, he tested genetically normal. Ugh, not a time to remember.
Triple marker test is a blood test that measures levels of AFP (alpha fetoprotein, a protein produced by the fetus) , estriol (an estrogen produced by both the fetus and the placenta) and hCG (produced within the placenta). They look at a number of different factors including age, weight, ethnicity, blood results and estimate the chances of abnormality.
High levels of AFP may indicate a neural tube defect such as spina bifida or anencephaly. Low levels and abnormal levels of hCG and estriol may indicate Trisomy 21 (Down Syndrome) or Trisomy 18 (Edwards Syndrome) or another chromosomal abnormality.
Double, triple or whatever, these are screening tests only, very important to remember, not a diagnosis. Results won't make a difference for us anyway, we wouldn't terminate, just prepare for a special needs child.
