I'm in the same boat. I'm 19 weeks today and I haven't felt anything, that I'm aware of. I lay in bed every night and put my hands on my belly to try to feel something, and nothing yet. I was at the doctor a little over a week ago and she told me that this is normal, and I probably wouldn't feel anything for about another month. That made me feel a little better, but I know what you mean about wanting to so badly and worrying that something is wrong. We have our big scan Monday (if they don't cancel my appointment for me again) and I'm terrified of hearing bad news.
Also, I just started showing, and by showing I mean barely. I wore a dress to a wedding last night that I bought prior to being pregnant and it has an empire waist (excellent choice now that I am now pregnant!) and hubby and I both said I looked pregnant in it. Although, this could have just been in our minds because I was waiting at the bar for a Sprite and a really nice old man came up to order a drink and noticed I was being ignored. He said that I have to be loud, and asked me what I was drinking because he was going to order it for me. I told him Sprite and he called me a bore. I told him no, I was just pregnant, to which he got a good laugh out of and told me that I had him there. He was really cute in his defense, and as we were leaving the wedding he offered to help me to the car because it was raining!.
