Apart from what is given in the above response post:
after logging in you may click on the Articles" link on the blue band on top of a page. In the opening page you can see 'My Articles'. You may click on it and know the status. You may also click on the other alternatives also there. It take some time for an article to be approved.
Articles which are just submitted and not yet reviewed by editors will be in the list in queue under 'New submission'. If they need some changes and re-submission, they will be seen under 'pending'. If you find your article listed there, you have to revisit your article, read the comments there and do the necessary changes as per suggestions. The deleted articles will be listed under 'Deleted' link.
As you are new I am trying o clear a possible doubt. Did you check "Article is ready to publish" on the article submission page when you completer your article? If even after going through al the actions suggested here and you are not able to see your article, then your article may not be submitted properly and the button may be showing against 'Not ready to publish yet'. Please change that and make the article ready to publish and save and submit.
Let us keep faith on ourselves and work sincerely, not leave everything to fate.
