Hi Tina
Having a baby can be a very positive experience, but Melanie's right, it's a major upheaval and not a cheap one!
However, while you're looking at settling your own lives a bit more and finding work, there's no reason why you can't start to eat the right things to put yourself in better shape to get pregnant. It's not always about buying expensive supplements or strange diets. Check out ThinkBaby's conception pages to see what kinds of food and exercise can help peven before pregnancy. This in itself is a great way to feel more positive for everything you do.
Good luck in the near future and in the long run, when you and your boyfriend feel the time is right to try for a baby.
