Light period

I usually have pretty light periods, It usually brown stuff with a little bit of blood, it’s always been that way. It started Wednesday into Thursday, brown stuff, and when I wiped, some blood, and now it’s just brown discharge and a little bit on tinted red discharge. There were definitely pieces of my lining shedding, but should I be concerned that it’s so light?

I’m on BC, taken perfectly everyday, for my period on the normal day, and normal spotting a day before hand.
