Kevin is right, momentum is the key.
You said you put a lot of effort into writing those two articles.
Let me ask you, how many have you written in the week since you submitted them? Hmmm?
Depending on the niche and specific keywords you've chosen to compete for with your articles, you may need a LOT more to see decent, regular traffic.
If you choose a longtail keyword (4+ words) that people are searching for and has little competition, you can get traffic almost as soon as your article gets picked up by the search engines.
If you writing for a competitive keyword or niche, your article may go pretty-much unnoticed, which is why you need a magnetic title, like Davin suggests.
There are plenty of people out there writing 10 or more original articles EVERY DAY to stay on top of their niche.
Keep writing! A few hits a day from each article will soon add up.

PS. It is no use to you if people just READ your article, they need to be clicking through to your site FROM the article for it to be of benefit to you. So, make sure you write an enticing Bio, make your site sound worth visiting, or post Part 2 of your article on your OWN site.
Saying "For more info on <My Niche> visit my site" just won't cut it. You've gotta sell the click!!!
