Jenna, I'd say what you're feeling is completely natural and nothing to be embarassed about. After all, every pregnancy is different, and I was just as freaked out by some things this time around as I was with the first! I think the thing that gets us all is that the whole thing is so unpredictable and out of our control - there really is nothing much we can do besides eat healthy, look after ourselves etc to influence the outcome of things. We have lots of info about all the things that can go wrong and it's natural to worry about them from time to time I guess. Pregnancy hormones are probably also stuffing with you a bit! Take it easy, let yourself be freaked and talk to your DP. All the best for a healthy pregnancy!
