Aw excited you most definitely have not let anybody down! Don't you dare think like that.
For one, you've carried your baby for 38w so far. (Bet your DH would crack after 2 mins)
Secondly, 38w and you only now needing further input with regards to BP? I think that's bloody marvellous. Job well done! Plus you got tea n scones out of a matron, that's some a achievement in itself
I bet you're like me and so over the whole pregnancy lark that anyone says somat the wrong way and you don't know how to handle it.
I was watching some West Wing earlier and was nearly greetin at a scene. No real reason to as it wasn't dramatic, but there you go! Tissues at the ready.
Besides, I bet baby is just peachy in there, all comfy swimming around. It's your poor body that's been going through hell!
Now, go demand lots of sympathy from you DH cos you have to take tablets. 
just for you
