Is this normal on BC?

I’ve been on Junel Fe 1/20 for about three months. Since then, I’ve noticed I don’t really have a true “period” anymore. I have dark brown discharge that lasts between 1-2 days. There is no fishy odor or smell. Is this okay?? I’ve heard a lot of bad reviews regarding Junel, but this is the only issue I’ve had with it.
