Congrats to Eavers! lovely name and you sound very contented.
Quick message to MrsBigz. I didn't have invasive testing for any of my pregnancies. The first one (DD1) was low risk. The second (Turners baby) I had a risk of 1 in 2 of chromosomal problems (not T21 - that risk was lower, not sure why; I was high risk for T18, T13, Turners) but the baby was not going to make it regardless of whether it was chromosomal or not, and they couldnt do cvs due to placental position, and I didn't want to wait for amnio, so terminated without testing (had postmortem done later). Next time around, was SURE I would do cvs regardless of risk, came out very very low risk, decided against it, consultant told me T13 and T18 would be evident at anomaly scan but T21 might not be. Decided to wait for anomaly scan since risk was apparently v low. Got to anomaly scan, baby had renal agenesis (not chromosomal, not detectable via cvs/amnio) and thus couldnt survive life, another termination. Fourth pregnancy, was less scared of chromosomes than renal agenesis, tbh, but was again very low risk (1 in 37000 of T21, and even better odds for the others) and didn't have cvs/amnio, on the basis that the 20 week scan would show the big chromosomal problems, but it was made clear to me that it might not show T21. Anyway I had scans every 4weeks leading up to Babycan't (now TalkingToddlercan't!!!) and all were very normal, but I confess, I had a niggling fear of some invisible chromosomal problem until the end regardless. Not helped by reading an interview with India Knight, mother of a child with Di George/io syndrome, who also had frequent scans in pregnancy and nothing showed up until after the child was born. However, I realized that there are no guarantees in pregnancy. A clear amnio/cvs doesn't mean the baby might not develop abnormalities in utero, maybe more serious than T21, or during birth problems, or even along the road after birth. I guess what matters is deciding what level of uncertainty you can live with and continuing with that. For me, the cvs/amnio wouldnt have been all that reassuring since I feared other things too, and so given my very very good odds it felt like something that, if it did happen to lead to mc, would make me feel very guilty since it would be my anxiety, not medical judgement, that caused it.... But I would have had those tests had my risks been worse. And I would have needed them.
Oh, this is so longwinded, but I guess I wanted to say: unless your odds come back high risk, then whether you have cvs/amnio or not is really down to how you feel, at the time, that you can cope with not knowing for sure. Bearing in mind that you can find out for sure that the baby doesn't have T21, but not that it will be healthy. Your fears, unlike mine, centre around T21, because you have been through that (I haven't) so maybe cvs/amnio would be what you need. But do wait and see how you feel. I think instinct is a good guide.
Phew, what an essay.
Mishtabel (do you know, I always want to shorten your name, because it feels long to type, but I hate the idea of missing out any of your girls!), how's your DD? And have you reached any conclusions about home schooling?
Good luck to all you pregnant ladies. Looking forward to more birth stories. Is Manitz okay? she's been quiet lately, no?
