Any insight? TMI pic attached

Hello all!

I don’t want to post a long story, but I’m looking for some clarity. My period returned a few months ago after having my daughter last September. It has been pretty regular starting around the 1st-3rd of each month. This past cycle I got my period on the 6th so I was 3 days late but hardly had any symptoms. It started off pretty heavy with hardly any cramps which is unusual. I bled the 6th-8th and spotted very lightly on the 9th. This is unusual for me. Is this an irregular period or has something like this

happened to anyone else? Any insight would be appreciated. Thank you! The picture attached is the spotting I had.
