One week back my boyfriend and i were dry humping with underwear on. both of us were wearing underwear. he did not ejaculate at all and he did not penetrate. it has been seven days since. i am now experiencing vaginal discharge which is a little more than usual. i am also experiencing breast tenderness near my armpits (this can also be because i went to the gym and did intense arm and abs workout which i usually never do). am i pregnant? i am a virgin and am extremely extremely scared. my period is due in 4 days but i'm still terrified.
