Any other nurses expecting in August?

Anyone else here a full time shift working nurse? 
Just wondering how you're going with early pregnancy and shift work, being on your feet all day and eating enough? 
I was looking after a lady today who was diagnosed with Influenza A 8 hours into my 8.5hr shift :(  No one originally suspected so there were no respiratory isolation precautions until we found out. I've had a flu shot 9 months ago. I'm sure I'll be fine but I can't say it doesn't worry me a little. 
Would love to hear anyone else's experiences.
