Had unprotected sex twice in the same day(Sept.27) Had normal period. I ovulated sometime around Oct.15. Then had unprotected sex again 3 days before my expected period, spotted(very light/pale pink-barely) the next day(2 days before expected period) off and on when I would wipe after using the restroom and had mild light cramping in my lower left side of abdomen, took a hpt(negative) same day, supposed to get my period tomorrow-but im not experiencing my normal pms symptoms? What do you guys think? Could I be pregnant?
