I don't know the regular duration of my cycle (I'm not sure if it's 28 or 30 days) but I had unprotected sex about nine days ago. (He did not ejaculate inside me) My period is due today but all I'm getting is spotting which is the first time this has happened to me. I'm not getting any other "pregnancy symptoms" but I am very stressed out with the possibility of pregnancy. Should I be concerned? I would love to hear your feedback; thank you so much!
