Don't want to get my hopes up .

Had an US at 14w6d , didn't find out gender until next day at gender reveal party . Me and my husband were sure it was going to be a boy but I wanted a girl . So now that the tech said girl I'm scared to get my hopes up and it's not a girl . I'm a first time mommy so I don't have any experience with what things should look like as for everything  is so small . Opinions please ??
