Ovulation bleeding

So my body has been regulating its self since I had my son a little over a year ago, before I had him and up until a couple months ago I never bled during ovulation, but the past few months I have started bleeding just a little bit when I start ovulating every month. Like I said I never bled during ovulation before a couple months ago, is it normal that my body I doing this now?

Its been a mix of light red and brown
