Initial Breakout on second course of Accutane?

I am taking Absorica and am on 60 mg a day (I weigh 115 lbs and am a female, 18 years old). My first round started August of 2015 and went into February of 2016 and I was only on 20 mg a day. However, my acne wasn't super severe (three large pimples usually). This time, my acne was much worse. Since this is my second round and a higher dose, will i get a bad initial breakout at some point? or should i expect improvement? my derm said i should only imprvove but i'm nervous.
