I can't believe that comment about the dog wannabe!!
Bloo, I have tended to avoid participating in too many discussions about antenatal testing, as I terminated a pregnancy last year, and realise this is not a decision that everyone would agree with. However, I just wanted to say to you, that you just don't know what is around the corner, as others have said, so in a sense it is not worth spending too much time being anxious about 'what ifs'. Last year, DH and had similar discussions about DS before our scan, and I had said I would not be able to terminate a pregnany for this reason. We hadn't even considered anything else that might crop up because there seems to be so much focus on Down Syndrome. In our case, unfortunately, our baby was diagnosed with Trisomy 13 at our 12 week scan, which is a lethal chromosonal abnormality, and we took the difficult decision to terminate.
Most of the women I am in contact with, who have similar experiences to me, also thought they would never terminate, also probably went to their scans preoccupied with DS, not aware of the myriad other problems that can occur. Only a small number of people that use the support email group I am a member of, have ended a pregnancy for Down Syndrome.
I'm not saying this to scare you-by far the vast majority of pregnancies are 'normal'. I just think maybe you should try not to focus too much on what might be but probably isn't, (if that makes sense). We spend so much time worrying about things outside our control.
Also as to whether they offer you CVS, amnio etc I am not sure that it is clear cut all the time just because of age, history etc. It was not suggested to my friend who will be 40 when she has her baby in June that she have a CVS. I will always officially be offered invasive testing because of our history, but in my current pregnancy the consultant did not advise CVS (because of good nuchal results.)Personally, if I can possibly avoid them, I will not have any invasive tests in this pregnancy.
Sorry for the essay-hope everything works out well for you.
