I'm assuming that you asked Child Support Recovery for a modification. Child Support Recovery can only modify child support every 2 years.
You can file a Modification lawsuit in district court if your child support would change by 10% (not income has changed by 10%). I would suggest contacting a local attorney to discuss your case and determine if modification can be supported in your case.
