Thanks everyone. Have had a busy few days and in hospital with only iPhone for internet access so is easyish to browse but painstaking to post. Lol.
Consultant appointment went well and anomoly scan went well. They couldn't check internal organs of twin 1 as lack of fluid makes it hard, but there did seem to be fluid in babies bladder, which is good. Otherwise, both twins seemed fine and are growing well, twin 1 was actually measuring the biggest, although not by much. Neither would confirm, but consultant and sonographer both though twin 2 is a girl, couldn't see for twin 1.
After the anomoly scan the midwife sent me to the day assessment unit as I had been getting very short of breath since mon/Tuesday. It turns out I have a pulmonary embolism/blood clot in lungs. Obviously worried but the doctors think if it was going to cause a serious problem it would have by now and it's not a direct threat to the babies. I am on injections to treat which I will need to continue for the rest of my pregnancy and afterwards.
The major worry for me now is that they have discovered I have bacterial vaginosis, which is an infection, from a swab they took on Saturday. It can cause early labour. They are treating me with antibiotics and hopefully it will clear with no problem. I don't have any symptoms so wouldn't have known I had it if it wasn't for the swab.
Good news is that the babies seem completely oblivious to all and are happily wriggling away. Also, the consultant has said they will consider resuscitation after 23 weeks if that is what I want, dependant on condition and weight of the babies at birth. They'd only have a very small chance then, (10%) but still a chance, more than they have now. Hopefully I can hang on and sail past 24 weeks.
Thanks so much to everyone for the support, it really helps a lot .
