With my DD I worked til 35 weeks, but really should have stopped at 34 as I fell over that week, I was just feeling tired and heavy etc etc. This time I wil be finishing at the end of 3rd term so at 28 weeks. Partly because I am on an end dated contract and only get paid maternity leave untill the end of it so I want to make the most of the 14 weeks paid as possible. Also it will be easier to find a replacement at the beginning of a term rather than halfway through. Plus it gives me some time to spend with DD before #2 comes along.
