I'm hoping to go till 38 weeks - mainly due to financial reasons. IfI don't feel well prior to 38weeks I'm going to take some sick leave. Like you, I don't know how I'll be by then, I may be incredibly tired or suffer from backache etc. Luckily I have 3 weeks (school)holidays from when I'll be 32weeks till 34 weeks; hopefully this will give me the energy to go another 4 weeks!
