can't point my WP Blog to Bluehost

I registered my WP blog (surensennaf1.wordpress.com) to (surensennaf1.com)and then signed up with Bluehost for self-hosting.. Since I registered my site just a while ago I couldn’t transfer it for 60 days so in order to get full access I was asked to point the nameservers towards Bluehost so I changed my primary site(surensennaf1.com)’s DNS to ns1.bluehost.com and ns2.bluehost.com and after sometime I tried to install WP through Bluehost and I did it correctly.

But when I tried to go to surensennaf1.com a new WP blog in my site’s name getting opened. Can someone help me out regarding this since I’m new to Bluehost?

I was able to access my usual WP dashboard but my site’s home page says
Welcome to WordPress. This is your first post. Edit or delete it, then start blogging! .. If I install WP then the page redirects to Bluehost home page sometimes too and when I tried to see any of my posts I’m getting This is somewhat embarrassing, isn’t it? It seems we can’t find what you’re looking for. Perhaps searching can help.

On my upgrades it goes on saying DNS needs to be updated
