Aligners come with a recommended wear schedule. The number of days each aligner is worn depends on the force that has been set by computer for each step of the treatment. That's why aligners may be worn for 5 days, one week or two weeks each. The pressure your teeth feel when a new, tighter aligner goes in triggers changes in the cells around each tooth that are responsible for moving it through the bone. This is a biological process, and it takes time. The fact that the pressure from the aligner has eased or stopped doesn't mean it's time to put your teeth under a new force. Stick strictly to the stated wear time for each aligner, so that you don't put the health of your teeth at risk or end up with unwanted effects.
This answer is for general information. Your own case needs an examination by an orthodontist.
