Once you have filed an answer to a temporary restraining,move out stay away order can you change it?

Upon filing my answer and having already filed it with the courts, I was reviewing it and noticed I had not responded to one of the orders. I do not feel comfortable with my answers due to the fact I was focusing more on the most peaceful way out of such allegations and a deflamation of character situation that has impacted a huge hardship on my life and my sons, and did not answer according to what is in my best interest. Do I have the option to re file an answer or change it during the trial?
