Can Accutane cause an initial breakout?

My sister's wedding is in 5 weeks and I delayed going for a consultation for my acne prone skin until the last minute and have just now been informed by the doctor that the medication could actually cause an initial breakout. How common is it for people to experience this with Accutane? Basically, should I risk starting the Accutane treatment now, hoping that should an initial breakout occur, it won't coincide with the actual wedding and my skin will look amazing or should I just not risk it and wait until afterwards?
