IBD during pregnancy

I am now 21 weeks pregnant.  Like I said before, I have good days and bad days.  This past week has been mostly good.
I have been worried about any effect the IBD may be having on my developing baby but happily, so far, there are none.  Every single test has come back normal and there's a healthy, thriving little boy in there.  So it's all good for now.
The Doctors test you for what they call Intra-Uterine-Growth-Restriction, in most cases this is apparently detectable through blood tests (if there's a reason for it to happen).  My test was normal, all gene tests are normal... so, I am sort of starting to relax about everything.
I also have an inherited blood clotting disorder called protein C deficiency, which puts me at a slightly higher risk of having some kind of blood clot.  This risk goes up in pregnancy.  So with everything else in my medical history this means I have to have a hospital birth.  I would rather use the birthing center in town and give birth in a pool but that won't be possible for me.  I will try to make the best of it though.
I don't want to say that I want a 'natural' birth because I don't want to feel disappointed in myself if I don't achieve that.  What I want is a healthy baby.
It's hard not to worry, I am by nature a worrier.. but I think everything's going to be ok.
