my first thought was 'grow up' but having taken the time to read your other posts, i'm not going to say that, and instead just send you an internet hug, and tell you just to pause for a minute, take a breath, and relax, by the sound of it you've been mulling it all over and got yourself a bit wound up/fed up thinking about the two weeks as impending hardship/minor disaster.
Working full time, pregnant, and handling a toddler is going to be difficult, so time to pull yourself out of the wallowing about it, and be a little proactive... think about the things you can do to make it a bit easier.
Don't worry so much about the housework, there's one less person, so less mess, just concentrate on getting a bit of laundry done and keeping on top of the kitchen stuff.. don't feel ashamed if you make life easier by getting some paper plates for the week if it'll help to just chuck them out after food rather than generating washing up 
Precook some stuff to freeze, or get some frozen meals in (if you can stomach them), see if any friends would be willing to help out with anything, i know i will always help out friends if they need it :)
It'll be ok, its only two weeks, so long as you get through each day with both of you fed, the rest can happen when you have the time/energy.
