Acne and pcod. Hormonal pills again?

I've had a sonography done almost 10 years back which showed multiple small cysts on the ovaries. Following that, the gynaec started me on hormonal therapy (contraceptives) to treat the pcod. I continued taking the hormones for a month or more and I discontinued them without taking a follow-up. My periods have always been irregular since they've started, sometimes skipping a month or two and sometimes on the heavier side for 10-12 days. Sometimes they are normal. Acne has always been a problem for me. 2 years back, I had a flare-up and the dermatologist had prescribed Doxy 100mg BD for a week and then once it subsided, 100mg once a day and then stopped them. For the scars she recommended laser therapy which I didn't go through with at the time. Now, I'm having mild flare-ups again. I've started Doxy 100mg again but it doesn't seem to be working. Should I go to a gynaec and start daily hormonal pills again? If it's going to clear my skin then I am willing to do anything. Please advise!
