Birth Control Risks?

Patient: Am I at risk by taking low-dosage oral contrceptives? I have recently started taking birth control pills (just started the fourth month) to relieve cramping pain during my heavy periods. I am 17 and have not experienced any problems so far but I have been warned of the dangerous side effects of the pill and am wondering how likely it is that I will experience them from long-term birth control use. In addition, I have found out I have three ovarian cysts that are not harmful yet, unless they grow larger. I have heard that ovarian cysts are common but am unsure if birth control will worsen their condtion or if birth control was even the cause.
