Confused!!

I'm a bit confused so I thought I could maybe get help. My fertile window according to my app was June 8-14 with the 13th bring my good day to get pregnant. Well the 13th i had light pink when I wiped. I had sex the 11th and the 14th. The 15th I had weird cravings, like I wanted EVERYTHING. It only lasted that day. Well yesterday  I discovered weird discharge like a lightish orange/light brownish color. Never had anything like this before. Today I had more of a brown discharge. My period is due in about 5 days. What do you think my chances of being pregnant are?? Or am I just freaking myself out for nothing?!
