"i started sprintec at 15 to regulate my periods and as a birth control and have been on it for the past 4 years. during the first month i experienced mood swings and irritability, but by the 3rd month i was fine. it&#039;s eased my period symptoms (terrible cramping and fatigue) and proven highly effective as a birth control. i&#039;ve recently experienced breakthrough bleeding from taking it inconsistently and am going to take a break from it. i definitely recommend this pill."
