How likely is it that im pregnant?

well im 21 and i had sex the fourteenth of june. yeah i kinda did it without a condom for like one or two minutes then my man put on a condom. so we always use protection but idk why we went all the way this time. were dumb. i know he wasnt close to getting off so i just wanna know how likely it is. i been having menstrual cramps for the last few days which always happend right before my period. but now im thiniking it could be that im pregnant but then im like idk if it would happen in two weeks the pregnancy symptoms so yeah how likely is it.
