Roth IRA Income limit question

I recently began investing the max annual amount to both my wife and my Roth IRA. However, this year I started a nursing travel contract which, in combination with my wife's salary, will likely put our household gross income, if not become very close.  My question is that I've already contributed and invested the max $6,000 to both Roth IRAs for this year. Assuming our combined income will likely, though not guaranteed, exceed the max income to contribute to a Roth IRA, what do people recommend I do at this point?

I have read multiple articles on ways to go about doing this but I wanted to poll some people here.  If my investments are doing well and continue to do well through the rest of this year, would it make more sense to pull out money now or wait until the end of the year?
