Currently 33 weeks but was hoping to stay on at work until 37 weeks. Bottom line is that I just couldn't do it. Work involves sitting at computer for 9 and 10 hr shifts, and due to third trimester swelling of hands and feet, I was desperately uncomfortable and knackered every day. Decided to reduce my hours but was still completely shagged at the end of each day.
Anyhoo, have stopped earlier than intended and feeling like a bit of a wimp. :(
