Should I Retake?

I took the June LSAT and got a 160. I continued studying and was getting low 160s on PTs. I got my August score back and got a 157. I'm trying to decide if I should cancel the August score and/or if I should retake the exam. Most of my target schools have a median of 161-164, so I'm below the median which worries me, but I'm also scared now that if I take it again I won't improve again. Any advice would be appreciated!
