TMI DISCHARGE PIC

Sorry if this bothers some of you... But I've never had any discharge like this before. Glow says my period is due tomorrow but another app I have been using for years now says it's due Monday.  But like I said never had anything like this before. I did however have very light brown spotting about 2 or 3 weeks ago. Is either of these a sign of pregnancy? I've noticed mild cramping in my back and stomach. I just had my son in February so I'm not sure what to think. I had an extremely easy pregnancy with him.
