Marianna, I think as long as you're not having cold feet about the actual wedding, everything will be fine!
Can you be more specific about why you are nervous about the dress? Does it make you feel self-conscious about your body? You say you have a nagging feeling that the dress is not suited to your figure. How is it revealing? Does it bare your upper arms/shoulders/chest? Most tops don't do that, so I can imagine how it might feel a bit odd at first, so maybe that's why you're feeling doubtful. But I bet it looks great. I can't offer more ideas without a picture, but I do think that your dress should make you feel like a goddess, so if you can pinpoint WHY the dress is making you uneasy, it might lead you to some solutions.
I didn't have wedding dress cold feet at all. I loved it. It made me feel like a cross between Elizabeth Bennet from Pride and Prejudice and Cinderella. I did have a bit of last-minute panic when I discovered that the outline of my underpants -- any style of underpants -- showed through the dress. It was made of multiple layers of gossamer light, floaty chiffon, so even though it wasn't see-through, a bump showed over the waistband of the underpants. The problem was neatly solved by wearing no underpants at all -- only reinforced hose -- which made my mother freak right out, but that just added to the fun of the whole day, lol. What's a wedding without the mother freaking out a little?
