pregnant?

i had unprotected sex while i was ovulating, and he came in me. this was about a week ago. i just used the restroom and i'm having some spotting. it's like a light pink, and had some droplets of blood. i'm not supposed to get my period for another week and a half of so. and i know that it's too early to take a pregnancy test. but i just have a guy feeling that i'm pregnant and i'm super scared.
