Help, am i pregnant already?

Patient: I am currently taking the birth control pills, me and my boyfriend are sexually active. I was on my period last week and stopped 2 days ago. I was on my sugar pills when i had my period, I got off it Saturday. I didn’t take my pill Sunday Monday, or Tuesday. Monday i had unprotected sex and later Monday night i went home and i was a little spotting. But it went away. Tuesday (today) i realized i have a brown discharge. What does this mean?

Symptoms: Discharge, cramping, spotting
