Confused 😭🤦🏽‍♀️

So for the past few months my period has been off the wall. Some months I don’t have it sometimes it comes and it’s only 3-4 days( not normal for me) and then you have the months where it becomes weird every time I’m about to start my period a brownish color starts forming then it turns red then back to brown but some months I get 3-4 days of the brownish color and then it just stops what do I do 😭🤦🏽‍♀️
