A lot of brown spotting help

angela

I’m on the generic seasonique birth control which is for a extended cycle in which I would only get my period every three months so far I’m only on the second pack second week of my three packs and i have been having a lot of brown spotting at first it was heavy breakthrough bleeding but it slowed up I’m just wondering will the brown spotting stop eventually? Or will it continue since it’s a low dose birth control?
