Hello!
Wow you can tell I've been off work today, I've posted loads!
The obstetrician is so lovely. I told her ibwas having some bad feelings about this pregnancy, like it might go wrong, and I wasn't sure why and whether it was just because it feels like there is so much going on health wise or if it's just because I am not thinking about it in the same way as my first. She said she thought once I'd had the appointment with the clinic in London this week to confirm/negate worries that I might have a genetic blood vessel condition that I would feel better. But she did a quick scan to check the baby was still ok and it's heart was beating healthily, and there it was wriggling away. It was so nice of her to do that.
I don't have to have the heparin unless the London clinic says its sensible. So that is good. I have to have extra scans at 28, 32, 36 and 38 weeks to check growth (because of my ileostomy). If it is starting to struggle I might have it delivered early one way or another but hopefully it will all be fine. Same if I get lots of problems with the ileostomy blocking, it might have to be delivered early. But in all probability it will all run naturally 
I have to have a CT scan in the third trimester of my chest to check that my lung circulation is still ok (I had something called an AVM which is a bundle of veins that shoukdn't be there and stops your lung circulation working efficiently). The AVMs are well known to get bigger when you are pregnant. This has risks. My AVM was "fixed" - blocked up with little coils - but there's a risk I might get new ones hence the CT scan. I don't really want to expose my little baby to the contrast and radiation though... A discussion to be had nearer the time I think.
My iron is a bit low and she wants to top that up now rather than wait and have to do more to fix any problems later so I'm going on a low dose of iron. She thinks it night help my mouth ulcers too and generally help me feel better, but she suggests I wait until I've finished my antibiotics.
So I'm quite happy and feel quite well cared for. This little bouncy baby feels so precious, I just hope it works out ok.
