I've been well with both my labours, so I can't say what happens then, but my experience with being ill at other times is that my body only seems to focus on one thing at a time Recently I seemed to have a few days' break from the all-day-nausea which is morning sickness because I had a nasty cold (I'm not sure which was better, mind you!) I reckon your body would focus on the labour, and you would probably 'forget' about the cold for the few hours while in labour and birth. Mind you, it would probably return with a vengeance afterwards if my experiences are anything to go by!! Hope you're feeling heaps better soon and don't go into labour quite yet...
