My period ended on wednesday and i had some unprotected sexual activity with my boyfriend the next day. although i'm still a virgin and we didn't have vaginal sex, he climaxed pretty close to my vagina. is there any chance of pregnancy?

It is very, very less likely because of many reasons. The timing is too early for ovulation. Then assume you are ovulating early, conception only occurs if somehow semen drips into your vagina. Even with that, conception is not that easy with that amount of semen and if any active sperm may be able to reach the egg. Although I would not say "never" in medicine I can probably say you are safe.

Pregnancy is not possible in above circumstances. Contraception remains otherwise key in avoiding undesired pregnancy and associated anxiety, specifically when intercourse becomes possible.

While you are not at risk of pregnancy from this episode, your behavior is putting you at risk of pregnancy and STDS.
