take action emergency contraceptive

Chelsea
so i took the pill a week or 2 ago we used a condom and stuff but i also took the pill because we just wanted to be on the safe side. We are pretty sure he didn't cum in me either.  I started feeling headaches, cramps, tender breasts, nausea, diarrhea and i had spotting with some blood as well. I'm scared of what's happening could i actually be pregnant??
