Late period help!!

Hi guys, I took plan b back in June after an incident 2 weeks later I got bleeding that lasted shorter than usual and was brown. On July 29th I was meant to get my second period... ended up being 11 days late and coming August 9th.... I sit here 2 weeks late for my period a nervous wreck as it's so late and I keep getting this heavy white discharge for a few days now. Could I be pregnant? I'm freaking out...
