Pregnancy possible?

Jaclyn
Hi ladies. I'm kind of freaking out. I had unprotected sex on days 7&8 of my cycle. I know the chances of pregnancy are low. But I am recently off the pill (took my last pack in December) and since then my cycles have been kind of unpredictable. I'm not sure when I have or will be ovulating. My question is...if I do ovulate on day 14, what are the chances of getting pregnant from sex on day 8? Anyone become pregnant this way? TIA.
EDIT: I am currently on cd12. Have not taken any tests bc I know it's way too early. Currently I'm experiencing some mild pressure/cramping in my lower abdomen.
