I stopped work at 27 weeks as i was also studying full-time and something had to give. It was nice as i was able to really concentrate on being preg and taking care of myself. I was also doing hypnobirthing so i was able to really concentrate on that..... BUT things were quite tight financially. My job was also one where i was on my feet. Had i had an office job of some description i would definately have stayed until much later. Things do get a little boring and as mentioned by others think of all the lovely things you can buy bubby.
