The ear thing doesn't sound good. Get yourself off to the docs and get it checked. Sure you haven't put a pea or something in it? Lol.
A weeks holiday is just what you need. Maybe after a proper rest you'll be feeling better and ready to go back.
I'm not expecting to hear about the job any time soon. I'm beginning to wonder if I actually want it. I do want a job, of course...but this particular job involves a lot of lifting and it's very physical. Plus, as it's for the NHS, if I get offered the job I'll need to go to their Occupational Health for sign off, which means declaring the pregnancy when I would prefer to wait until I was a lot further along!
