I am 20 years old, and this is my first time taking birth control pills. I am currently on my first green pill (sugar pill) of my Ortho Tricyclen Lo 28 day pack. Although, I have been spotting a dark brown, thick, discharge for 4 days now. I have also been experiencing period symptoms, light cramping, tender breasts, moodiness. I've been taking the pills consistently everyday, and have never missed a pill. I have been having unprotected sex with my boyfriend (after the first 7 days of taking the first pill). Could this brown spotting be my period? Could this be spotting from pregnancy?
