I start it bleeding red on saturday and the day after brown stuff start it coming out and it havent stop and i just start it a new birth control and ?

This can be normal: Any time you start a new birth control method, you can experience abnormal and break through bleeding. I assume you had a negative pregnancy test prior to starting your new birth control correct? I would watch your bleeding for a few weeks, and it should improve. If not, sometimes we can add a hormone for a few days to help with the break through bleeding and normalize your bleeding
