Would there be any tax implications of recharacterizing a contribution to my Tradition IRA over to a Roth IRA if it occurs within the same calendar year?

In the beginning of the year, I made my annual $5500 contribution (after taxes) to my Traditional IRA because I anticipated I would not be eligible to contribute to my Roth IRA. Since I got laid off and did not work for several months during 2017, I am well within the AGI contribution ranges for a Roth IRA.   Would there be any tax implications of recharacterizing and moving the $5500 over to my Roth IRA since it would occur within the same calendar year?   Also would I just re-characterize the $5500 or would I need to figure out how much this money grew and move that amount as well?
