Dan, I'm feeling exactly the same way. I have been so sick right from the start of my pregnancy and the whole way through that I have done absolutely no exercise. I must have spent at least 4 months straight on the couch. So, I have absolutely no fitness left whatsoever and am really worried about how I'll cope with labour. I was telling a friend how worried I was about it and she said she was the same way (she had a very bad pregnancy) but come labour she didn't have problems at all so maybe its one of those things that our body just somehow manages to find the reserves it needs? I'm hoping so anyway
