Thanks all, gutted it's still not better news. @snowwhite2020 yeah it's the fluid in the tummy, it doesn't appear to be a cyst now, and the tummy is just really full, pushing the heart, lungs and other internal organs upwards. The heart is still beating but is struggling. @champoopapi next steps are referral to EPU at University College Hospital in London for blood tests, amnio (I think) and genetic testing/karyotyping, and for them to scan me. I asked the consultant today if they could try drain the fluid, he said UCH might consider this but he's not sure if it would help.
