Stopped nursing/tretinon cream acne: medication for 3 weeks now and am experiencing the worst acne I have ever had.

I recently stopped nursing after 11 months and suffered the whole time with skin issues. I started back on the combi birth control Loreyna (generic for Yaz) and she prescribed spironolactone/dapsone cream for AM & Tretioin for PM. I called and they said this outbreak is normal. She prescribed Doxyclone as well. How long before things get better? Should I stop and let my hormones balance out first? My skin was bad before but this is much worse. Thanks.
