Hormonal Imbalance

Patient: I was diagnose of hormonal imbalance 3 years ago. I undergo ultrasound, and they found that I have retroverted uterus. Before i am experiencing a 15-days mestral period. My ob-gyne prescribe a contraceptive pills that I need to take for 6 months. But unfortunately I wasn’t be able to finish it. I just took the pills for almost 3 months. Now, my menstral cycle takes for about 36-42 days. And I am also having pimples. Do i need to take again pills?
