Should i count my steps in the 300 intermediate hurdles?

I am a 300 hurdler and i have district finals on thursday. I've been have problems with stuttering only over the second hurdle. My count to all the hurdles is supposed to be 15 but i sometimes mentally think im either too close or to far from the hurdle to take off. Would it help me to count 15 steps in my head to the second hurdle? It is very important that I dont stutter in this race.
