Hi I Had Sex Like 2 Weeks Ago And Now

Hi I had sex like 2 weeks ago and now I'm like having sore breasts and on Monday morning I fell trying to get up , my period should be coming this week , I was just wondering if I could be pregnant because I feel like it's too soon for a test , I've had lower abdominal pain & have had some light blood when I wipe , I know it's not my period because that shouldn't come for another week
