Thanks again all.
Scan went well. Both babies fine and moving, although obviously twin 1 can't move that much. Twin 2 was definitely swallowing on the scan, which was fab to see, he/she took a big gulp. The consultant was trying to see if twin 1 was swallowing, but wasn't sure, although said it is possible as there was a small pool of fluid by the face, as there always has been.
The bad news is, the blood clot I had/have seems to have complicated thinng far more than I had realised. The haemotologist has spoken to my consultant this morning and is concerned about me bleeding in labour/during the birth as I am on such a high dose of clexane. She is also worried about the continued effects of the clot as it starts to break up. So, they are admitting me to the hospital tomorrow with a view to putting a 'greenfield filter' in, which apparently acts like a kind of sieve to in an artery to stop any bits of blood clot that break off going to my heart. (obviously very serious!) Plus, I will stay on the clexane, although will have to stop it when in labour. I also need to see an anaesthetist that deals with patients on clexane and similar to find out what my options at delivery will be.
They are also trying to decide which hospital I should give birth in. My booked hospital don't care for babie sunder 28 weeks usually, but have cared for some 26 weekers. (I need to see a neonatologist about that really) but unless the hospital that do have available cots then there isn't much point in tranferring me. I'll get the steroids Sunday and Monday either way though and then again at 28 weeks if I am still pregnant by then.
So, I'll be in for the foreseeable future, maybe until delivery. Fun!
