Mrs I'm so glad you've come back to us. I've heard about vanishing twin, sorry it's happened to you, but can understand why you feel the way you do. My sister is expecting twins just now, and her tests went fine, but I'm not sure how the vanishing twin might affect things. I'm sure the hospital probably come across this more than we would think and should be able to guide you.
Stranded what a shame about your PIL, they could at least have pretended! Hopefully your parents will have a great response for you. I'm starting the process of telling the wider world now, although I really should wait until the NT test is done on Friday, but our private scan was so clear.
I am being spoilt rotten, puppy is being walked and toileted for me (in fairness DH does that at home just now), drinks brought to me, shame it's ribeana not the traditional G&T, and my favourite food all cooked. It's things like proper macaroni cheese, which takes ages to cook so feel bad asking DH for it, but my mum just rustles it up no bother.
