To quit job or not

I'm in a dilema, whether to quit job or not. Work is becoming more streeful off-late.At this point of time, when we rae planning to go the family way, I dont want to take stress. I want to give birth to a happy and a healthy baby! There I said it..But, the thought of not earning (since I've been earning even before passing out of college, while I was an intern), not able to see the bank balance grow, need to think before spending (not that I dont think now, while earning).I'm neither a shopaholic nor a spendthrift. I feel I can manage not working too. Once I conceive, I will anyway quit unless the office wants me to work from home. God, please help me make up my mind and take a decision that is good for me
Thanks!
