If you've had unprotected sex (when a penis enters your vagina without a condom or any form of birth control) there is a possibility that you could get, (if not already are) pregnant. Why in 2017 this is still such a hard concept to understand. The only exception is if there are medical/fertility issues involved. To those who are actually trying to conceive, my apologies, but for those who are careless....become a little sharper. Denial is a bitch, and won't make that possibility any less.
