Just looked at BTC.com and found next difficult level will be increased by 18% in 6 hours. Does it mean the BTC price will go up another 18%

Just a question I havent been able to wrap my head around quite yet:
If I have been mining at kano from 11.dec until now, will the shifts I produced before this diff increase, get paid according to the diff when they were produced, or with the new diff?
Cheers
