Brown Discharge in the middle of cycle?

i got my last period on january 15 that lasted until the 26th. (my period is irregular and im going to start birth control my next period) i was having normal discharge for about 3/4 days and then it started to brown again. i usually get brown discharge either before or after my period but this was in the middle of my cycle so im confused. also sometimes it is chunky but im not really concerned i just dont know why im getting brown discharge and im not even close to my period. also i dont have sex currently or recently so its not that. if someone has had anything similar or know what could be going on please lmk!!
