I got the contraceptive shot. Since then I have had a few acne break outs. Is this the worst it will get?

I was on two cycles of Accutane a few months ago, and since then my skin has been amazing; however, around a week ago I got the contraceptive shot. I read online that people experienced severe acne after using the shot. Since then I have had a few spots flare up and break out. I am just wondering if it will get worse or because I was previously on Accutane if this is the worst it will get.
