I got on the pill when I was 16 as a regular user. I also tried it at 13 for a short time to help with break outs. I had always thought that I was lucky, despite many mistakes (missing pills), I had never gotten pregnant. I thought the pill was amazing until the time came when I was put on Yaz. Then, I started having a lot of problems. Around that time it was discovered that I had small ovarian cysts. Because I was a newly wed, and I did want children, I decided to start going to acupuncture for the insulin resistance that was apparently causing the cysts. About a year after treatment I got a wonderful surprise! I was pregnant. It wasn''t until after I had my daughter and my body "reset" itself that I realized, I really don't know if I ever had ovulated before. The ovarian cysts from before were explained to me as being eggs that were not mature enough to detach, so they would stay on the ovary. I believe that it was the introduction of the pill into my system at such a young age that probably disrupted by body's normal balance since I was put on the pill briefly within two years of starting my cycle. I am off the pill and using the copper IUD. It has its drawbacks, but its worth it to know that I am still ovulating every month. I will never go back to any hormonal birth control ever again.
