Brown gray milky discharge. Infection?

I had unprotected sex on 3 aug. My period end on 2nd aug i was hving little flow on 3rd aug also. My normal cycle is 32+ days. I took unwanted 72 after 1.5 hrs of having sex. I had eaten papaya on 6 aug and 7 aug .after taking pill i get light flow on 10 aug and blood spotting for 3 more days, after few days on 23 aug i get sticky red brown colour blood clots discharge once a day for 4 consecutive days. I was dng little exercise after this i stopped it.I did pregnancy test on 28aug and 1 sep it is negative. I again had dat red blood clots discharge from 2sep (once a day)  till 5 aug with mild bloating pain. I get intimated this time protected on 6 aug and i bleed. I did pregnancy test on 12 it was negative. After that now i am not having any bleeding or clotting just brown gray milky vaginal discharge without any foul smell. Is this color vaginal discharge normal? Is thr any infection?
