Glad you're on the mend eallison it sounds pretty awful.
spam I hope you get to the doctors ok, as lovesmycake said, could you not cab it? If you can walk it, it can't be that far, a cab wouldn't cost much.
Found out yesterday that a friend of mine (one of the few that lives near me) is pregnant and only 2 weeks behind me! I'm very glad to have someone IRL to go through it with! We already have DDs that will be in the same school year, so assuming everything goes ok, our second ones will too! 
I hope all those with sickness feel better soon, and good luck to all those having scans today.
