I have been of Accutane for about 5 weeks and going back on. Will I break out worse again?

I've been on accurate since mid November pretty consistently (with small gaps due to getting the prescription mailed but usually less than a week). I was told I had cystic acne and although it was worsened at first it started to clear up. I've been off for about 5 weeks now due to a blood work issue due to an illness and am now about to start it again. If I've been off for this long and start taking it again will I go through the acne getting worse again? Age 17 weight 145 height 5' 10"
