Launched Google Adwords Campaign and irganic rank dropped immediately

I launched a google adwords campaign about 8 hours ago for my main keyword. Immediately after that my website, which had been number 1 for weeks for that same keyword, dropped to the bottom of the 3rd page. Has anyone else experienced this, will my website return to the top of organic results soon?

 

I think this is normal and within a three or four days it should return to first page.
