Lucy'smama - based on your experiences it's no wonder you worry! you don't have to apologize for that!
water: YES! I totally forgot about those cramps. I did have them, and they did feel like period cramps. Back then they didn't bother me, but for some reason they do now (as in, they make me worry sometimes). Well, I had them again at the end of the work day in a loooong meeting and I hadn't nursed DD in hours and hours so apparently it's not the nursing! At least I don't have to worry about that.
aspiring mama: WELCOME!!
as to how to calculate your EDD. the OB's go by a set standard, so if you want to talk the "lingo" with them, use this method. It's very easy.
get out a calendar. go to the first day of your last period and count 40 weeks from there. That's your EDD.
Of course, if you know when you ovulated and you know if it was longer than 2 weeks after your period then you can be more precise (then it would be 38 weeks from your date of conception). but OB's don't go by that so that it's all standardized (most women don't know when they O'd).
alcohol: I actually enjoyed wine up until I was about 7 months and then all of a sudden it tasted terrible to me. I only drank about a half glass and then only once or twice a month if we went out for dinner (remember those days pre-baby when we went to restaurants? lol). I totally respect mamas who don't partake of any alcohol, but in fine european tradition, I believe a bit of the red stuff is healthy!
i do forgo caffeine though - I'm very gassy too! And caffeine does a number on my gut even when I'm not PG. For some reason, however, it doesn't apply to chocolate!! :LOL
