January LSAT too late?

I am going to be submitting my law school applications this month, but I’m thinking to retaking the LSAT. I got a 156 is September and am supposed to be retaking the test in a few days. However, I am not feeling confident enough that I will see any considerable improvement. Should I just bite the bullet and take it? Or should I postpone it to January and submit my new score after I’ve submitted my applications. Thank you in advance for the help. (I wish there was a December LSAT)
