Anyone had this before

So the day before my period was due I had brown discharge which is normal for me I normally have a quite heavy period for at least 2 days this month only 1 really & then just brown for days I logged my period as 4 days but felt it wasn't a proper period 5 days later & brown discharge sorry (tmi) started again I've read that this can be due to not having a proper period just wondering if anyone experienced the same & how long it lasts on day 7 now & still a little there.
