I have mine tomorrow and am so much more worried than I was with either previous pregnancy. I'm driving myself mad thinking through all the things that could go wrong, and all the things I've done wrong that could lead to a problem. We have a lovely evening arranged afterwards, so I'm trying to focus on that, but I couldn't sleep last night from worrying about tomorrow. I know things can and do go wrong, but I have no reason to think they will iywsim. I wish I could feel more positive about it.
