Is there anything that can help acne while weaning off of spironolactone and birth control pills to conceive?

I have been on spironolactone for 11 months now. My skin has been 90% clear for 6 months- actually almost 100% clear since going up from 125 mg to 150 mg in November. I'd like to conceive sometime over the next year, but I am anxious about dealing with the hormonal acne. I've started taking a DIM supplement about 6 weeks ago and tried to go down to 125 mg of spiro a month ago but had a few breakouts and went back to the 150. Any suggestions?
