Does anyone's stutter come and go during different times of the year?

Does anyone's stutter come and go during different times of the year? Hey everyone, I'm not really sure if anyone has experienced this before but I've realized that my stutter can be very noticeable from the months of august-January But slowly disappears during the months of February-July. This cycle has been happening to me from a very young age, any advice/explanation would be greatly appreciated.
