Please help! Am I still on my period?

My period was supposed to end on the 20th and it started the 9th. I’ve been having discharge like this since it was supposed to end. Since it was lighter is this just my lady bits cleaning itself out or could it be something serious. It’s also the 2nd day of my fertile week. This discharge comes out around every 2-4 house and it’s not anymore than this when it comes out.
