Should I be worried

So my period is pretty regular. (I’m on the pill) but I got my period earlier this month (lasted about 6 days which is normal for me) and then a week later I started spotting (brownish blood and it was a lot lighter of a flow) and I’m still bleeding but it’s not spotting anymore. (Still seems lighter then my period and still brownish red in color) it’s been about 3 weeks now.
