So sorry, sad73. Mt first baby was diagnosed with anencephaly at 21 weeks. She was a very much wanted and loved baby, and we were devastated by the news. We chose to have an induced delivery (I hate the word termination in this circumstance, and can't bring myself to say it). I don't regret the decision, though I'd never imagined myself doing it, and signing the form just about broke my heart.
I wanted to at least try to answer all your points:
I'm very sad that it looks like this baby won't make it.
It is awful and heartbreaking - in some ways it was easier for us, because it was so obvious, even to us, from the scan that she had no hope of survival. What you are going through is extraordinarily hard.
I feel uncomfortable with a decision to terminate (it seems so huge). Deciding to do nothing feels better yet I'm a very private person IRL and obviously I would have to tell lots of people (inc work) about this since the chance would be high that my baby will die before term.
I completely understand your desire to not talk about this in real life. That was exactly my reaction - I wrote to work essentially saying that, and people did respect my wishes. There is a useful leaflet from ARC which will help you if you choose to continue - there's also one if you choose to terminate, and ARC in general will provide you with lots of support.
The idea of having a still birth is very upsetting to me (and I guess any normal person).
Before I delivered my daughter I could not understand how anyone could survive delivering a stillborn baby. I dreaded delivering my daughter, but it was not as bad as I feared - it was terribly sad, but there were moments of just amazing joy as we held our tiny girl and said goodbye. I still remember it with peace and a smile.
It seems so counter intuitive to terminate because we wanted this baby. Based on the 2 scans so far, my partner thinks the least awful option is to terminate, though he wouldn't object if I disagree.
I absolutely understand this - I could never have imagined having a termination. For what it's worth, I don't feel guilty about it, and I've thought it through long and hard ever since. I miss my daughter so much still, though her little sister has proved a great distraction. P is, and always will be part of our family. Whether you deliver your little one early, or carry on with your pregnancy, this little one will always be your baby, and carried in your heart.
I'm frightened of the termination procedure, which ever one they suggest. I know this sounds pathetic. I' m not sure what they would want to do, I guess I would be between 13 and a half and 15 weeks by this stage.
It doesn't sound the slightest bit pathetic. It sounds normal and reasonable. I only have experience of induced delivery, and in the end it was a dignified and peaceful occasion, which brought us peace and joy amongst the sorrow. I hope someone else can tell you about the other procedures.
I've been iller in this pregnancy (coughs, colds and morning sickness) than in the last few years, and I feel responsible.
I've thought about this a lot - neural tube defects are linked to low folic acid, and I was a bit slapdash about taking fa, in hindsight. But really it's just plain bad luck - these things are so rare it is impossible to predict who it will happen to and why. You didn't set out to harm your child - you had very very bad luck. The chance of any of your illnesses causing the disorder is very small - I hope the CVS sets your mind at rest for this.
Sorry for going on, I have a lovely supportive partner but talking about it IRL makes it too real at the mo.
Go on all you like. Talking this through, in all its minutiae, is part of the process of dealing with it. It's important, and there are many many people here who understand.
I guess we'll do the CVS and see what happens after that.
I hope you get some answers which will bring you some peace and comfort. Will be thinking of you. Would also recommend the SANDS forum for support, both now and in the time to come.
