Extended Cycle Birth Contol Pill

Ba

Is anyone on an extended cycle pill (Seasonale / Seasonique or equivalent)? I’ve been on one since January after taking a break from birth control for a while, and I just keep spotting - days and weeks at a time. My doctor said to stick with it for one more full pack (3 more months) but does anyone know if it will get better? Is this normal for this type of pill?
