the only thing id be concerned about is that you may be develpong a psychological dependancy to gear bro. i am on a 20 week cutter right now which was originally supposed to be 12 to 14 weeks, and to me it is a similar situation as yours. i doubt you will cause any harm by starting early bro but look at it from a psychological standpoint. if a few weeks dont make much difference then why are you so eager to start back up? for me it was easy to stay on another 8 weeks or so beause i told myself i had let my weight dip too low and i wanted to regain a little LBM. but from a psychological standpoint i realize that somewhere in me is the fear of coming off. i dont know your particular situation bro, maybe you want to start earlier based on some deadline or so your cycle wont interfere with vacations or some other reason. but if youre just feeling impatient, ask yourself why.
