YAZ and acne ⁉️⁉️⁉️⁉️⁉️

Erin
If you were on Yaz (or something similar) and had acne, how long after starting Yaz did it take for your acne to clear up?
 
Yes I know the adverse side effects of this birth control (mood, blood clots, etc.). I was tested for a blood clotting disorder before I began taking it and got the go ahead. And my mood has actually improved 100% since I began taking it. BUT I haven't seen a difference in my acne yet and it's been almost 3 weeks. 
 
What were your expierences ?!
