The site that I got approved with had about 15 pages /posts of useful content, an about page, privacy policy, and good internal linking structure. I think the way people get round showing ads on a site devoid of content is to get approved first, with a content rich website, and then stick them on. I've even done it myself when I've been developing websites
Nothing you can do except wait. It takes up to 2-3 weeks If you asking about the site in your profile, it will be rejected.
