Birth control 9 months, bleeding for one month

Lorrie

First time mom, had my son a year ago. Been on the same birth control for 9 months. Now since Christmas I’ve been bleeding for a whole month with a few days off & on this past Friday-Sunday. Now I’m bleeding again.... have been having horrible breast pain & headaches... should I be concerned?? Any thoughts about what I should do? I have an appointment but it’s a month out 😭
