Five days before period had dark stringy discharge. light brown discharge when wipe. on birth control. just had bacterial infect.treated. rephresh pil?

Brown = old blood: Breakthrough bleeding (bleeding at the wrong time) is very common on birth control. It happens in about 1/3 of users. Its no big deal and usually self corrects over time. If you are not satisfied or it continues to happen then consider using a different birth control method. It is a common side effect and does not mean something is wrong or that the pill is not working. Rephresh is fine to use
