birth control
"I just started my second pack of Sprintec. I have had very irregular periods, the longest space between was eight months. After looking up what might cause this and ruling out pregnancy I found something called PCOS. I went to see a docter to get tested. After the results came back she put me on this. I got my period right on time with the pack. Normal length but a little heavier. I haven't experienced any side effects except maybe higher sex drive."
