Is it normal for acne to get worse before getting better with Spironolatone? 1 week post op.

I started taking Spironolatone a little over a week ago and have noticed that my face is breaking out more and my pores seem to be larger/more noticeable since starting it. I also got a Mirena IUD about one month ago. I have been on two rounds of Accutane and since that only worked for a few months, I didn't want to go through another cycle of that. Just wondering if this is normal and trying to be patient and stick it out for a few months!
