So I’m terrified. My last period ended on November 11th. Around the 20th I started having old blood brown discharge. It never stains my underwear but it’s always there when I wipe and all. My next period is due in 6 days. I’m on birth control so whenever I have se. Theres no condom. Prior to the discharge, last time I had sex was about 3 weeks before. Am I pregnant? Ovulating? Or just welcoming a new symptom to my cycle?
