Help!

Kalena
I am having a faded pinkish orangey discharge my last period was October 2, 2016 to October 7, 2016 I'm not really expecting my period until next month and i had sex twice or three times with my boy friend this month without a condom after my period, anybody may know what this means?? 
P.S. i am very irregular when it comes to my mestrual cycle.
