Scared i'm pregnant

Me and my boyfriend had sex on the 5th of my fertility window, we used protection but tried without it for maybe 10 seconds. I had little bit of blood after sex mixed with my discharge but i think it's because of rough sex, i have no symptoms at all, no morning sickness, no breasts pain, nothing at all, eve says i should get my period in 8 days. What are the chances and should i have any symptoms by now if i was pregnant? (Btw i had brownish discharge during my ovulation, is that normal?)
