Just jumping in on the discussion about worrying (sorry I haven't been posting much), I am also completely freaked out about the 20 week scan. Mine isn't until May 20th, which feels like an age away.
We are now telling people in our day-to-day life that I'm pregnant but I can't bear to do a FB announcement until we safely get past the anomaly scan.
I know even getting to that point doesn't necessarily mean you'll get a baby in your arms, but at this stage I'm worried about them picking up serious problems at the scan. And yes I've thought about the trisomies, spina bifida (esp. as my mum only revealed two weeks ago there is a family history), and all sorts of other things.
I've 'only' had one miscarriage, but I've also had years of infertility and failed IVF so I think my natural expectation is that I will lose the things I want - I'm sure many of us here can identify with that. We've all had loss of one sort of another, and it takes away the naive enjoyment that some pregnant women have.
Nevertheless, once we've got this far we do have a VERY good chance of taking home a baby at the end of it all.
We have to remind ourselves that 'today we are pregnant' and that statistically very few pregnancies end in miscarriage post-12 weeks.
I'm not the beacon for optimism, obviously, and I have more bad days than good days. Whenever I think about the anomaly scan I panic. But we can do this with the support of each other. One day at a time x
