On June 4th I had sex, I woke up today with some spotting, now my period is due June 13th but is usually late by a week or more. I did a hpt, and it was negaitive but that still does not mean anything. I have felt sick a little but sometimes I get that right before my period.I don't know what to do. This spotting thing is scaring, me and I don't want to tell my parents.. help?
