Guys am I pregnant

Ok guys so help me out. I will walk you through this. The red circle was the start of my period last month. I roughly have a 29/30 day cycle. **Keep in mind I’m sexually active** The blue circles .. I randomly had gooey brown discharge for 3 days . It wasn’t a lot .. the green circle was SUPPOSED to be the start of my period. & the purple circles is the off & on brown discharge I’ve been having. What’s going on? I’m about to be 6 days late.
