Brown spotting / blood

Since having my son and my period returning I always have what seems to be spotting/discharge before my period. It’s usually brownish black and lasts 2 days. Then I get my period for 4-5 days usually last 2 days are slow/light.

This time my “spotting” had like little clots in it.

Just curious if many women spot before?? I’m sure it’s normal l just feel like before pregnancy I didn’t spot before my period !
