Spironolactone question

I started Spiro (50 mg) about a month ago, and I'm not seeing ANY results - at ALL.  My 21st birthday is in two weeks, and I was really hoping I would be clearing up by then. I called a nurse @ my derm office to ask if I should up the dosage since I'm not seeing any results, but she said just to wait till I talk to the Dr. at my appointment (a week AFTER my bday.) Do you think I should start taking 2 a day so I see results my bday?  Any experiences with Spironolactone/how long it took to clear?  Thanks loves
