Marsup - when you have your scans tends to be dictated by where you live, but you and your families history can change it. Where I live now do them at 12 and 20 weeks where as where I used to live only did one at 20 weeks. However last time I had one at 6 weeks due to bleeding, and 2 every 3 weeks from 20 weeks due to my son having situs inversus (back to front inside!) and a suspected hole in the heart. A friend also had one at 12 weeks as she was unsure of her dates. I guess the more routine the pregnancy the fewer you will have.
Don't worry about your weight just let it do what it wants. It's quite common even to lose weight at first. Last time I lost 1/2 stone and apart from gaining that 1/2 stone back did not start to gain any more till 27 weeks then it just piled on!. I am 10+ weeks now and am 1lb less than I started at.
Presto - If your so much worse than last time it may well be twins - I've read people tend to feel v. sick when carrying two, either that or it could be a girl! What do you fell about having twins? We have twins on my side and dh is convinced I'm having twin girls this time, I do not think I'm sick enough for that to be the case, but would be v. happy if it was true.
Absolutebegginer + loubie732 your not alone with the feeling that it is still all so fragile yet. I never really thought about it with DS, but with this baby I just can't let it sink in untill I've seen the baby on the scan (19th) and know it's ok. I never expected to feel this way and I don't know why I do!
Tinyfeet - roll on two weeks. I've only had two days where I have actualy been sick, but as ds is only 17months it's hard work. The first day I was sick 11 times so dh had to come home to look after ds, and the second was yesterday and ds grabed my hand and tried to drag me out of the bathroom mid vomit!! It's the triedness that is killing me at the moment, I can't wait to get some energy back so we can go out again. Ds is missing it so much he keeps takeing me to the door and saying out, but I'm just not up to it everyday.
