Newly rider and a green horse

Question
My Tennessee Walker Stud is green broke but while riding he tends to gait side ways is this normal or how do i fix it because i just started riding horse about 4 months ago

Answer
Holy cow, you have only been riding for 4 months, you ride a stud that is green broke and you have not been killed.  I am impressed with your luck.

First I would not ride this horse before you did some good research on horses.  You are in a very dangerous situation.  I need some more info to help you.

How old is horse, who green broke him, do you use a bit, what kind, how old are you, is the horse kept in stall or pasture, alone or with other horses?
