I'm on birth control , where you only get your period every 3 months , after I finished the first pack & towards the middle of the second pack , I started spotting , then it was full on bleeding , no clots though . It was just blood , then it slowed down , but I'm still bleeding . It's to little for a pad but to much for a panty liner . . . . . . . . . . . . I'm so lost . Help ?
