Talk to Dermatologist on Acne/Hormones

Marital status: Married

If using any medicines pls mention the names and the duration of usage: cyprodial and fisol primrose oil

Complaint: due to having periods twice in a month and really bad acne, a month ago gynecologist prescribed me both the medicines. The doctor asked me to eat cyprodial for 3 months with 7 days gap after each month. Now the acne is still the same, I am still left with 1 dose of primrose oil and currently on that 7 days break from cyprodial. Got my periods on 15 dec (last periods 15 Nov) So many people told me that my periods now will never get normal if I keep on having contraceptive.

Please let me know if I should continue the 3 months course or leave it? Should I consult some other gynecologist? Or should I go to a dermatologist?
