pregnancy scare?

Phoebe

hey guys, so lately i’ve been having tender breasts and also i had this like brown blood/discharge come out of my vag, which i would think was signs of my upcoming period, but i’m on the pill. and i don’t know what it is, and i don’t know if i’m paranoid or what, but is there a possibility that i’m pregnant? or is it something to do with the pill??
