I can't imagine being pregnant, having something wriggle about in your belly Alien style. I do get the feeling like those last few days before you're due must feel like killer period cramps. The terrible rolling pains that make you want to cry from frustration more than anything else. I also imagine you're totally overheated and uncomfortable 100% of the time in your last couple of weeks. It sounds way too much like suffering. I guess the fear of pain, and birth in general, must subside at some point, otherwise why would anyone choose to put themselves through it?
I don't actually know much about the mysterious world of pregnancy - so my thoughts above might be totally incognisant.
