Expect your withholding to be less so you have less to pay your tax bill so you may owe taxes if you didn't withhold enough or your refund will just be less. Until you actually put the figures in the return you will not know.
FYI ... NEVER claim exempt on your W-4 if you don't qualify for doing so. If you wind up owing on the return the IRS can hit you up with penalties for doing that ... instead just increase your allowances on line 5 of the W-4 to 10 as that will do the same thing without the possibility of penalty.
