Brown discharge/spotting before period

So I am not due to get my period for another 10 days (i have 7 more days of active pills left) and I noticed small amount of brown discharge when wiping today. Is this normal? I’m concerned because I’ve already switched to a new birth control 3 months ago since I kept spotting/getting my period early and during my active weeks on my old birth control. Everything has been fine with this birth control - I have been consistent with taking my pills on time and my periods have been regular the whole time with the newer birth control. Thoughts??? And I am definitely not pregnant.
