Help what’s going on

So I am on BC and I use the patch so back to last Tuesday I took my patch off because I was supposed to start my period on the 29 or the 30th but I was 3 days late and my period was super weird I wouldn’t even call it a period (was only 3 days) now today the 5th I’m having mild cramps and very light pink/clear/brownish looking discharge. Could I be pregnant? I doubt it but I have had unprotected sex with my boyfriend more than once. This pic was from yesterday morning
