pregnancy without penetration? I am virgin

That depends on what happened to the semen and whether it were at a time of your cycle.

Would you be more specific with the details, please?

1. "8 days after my period" - started or finished?
   1. What date did your period start?
   2. What date did this happen?
   3. How long is your cycle (typically 28 days)?
   4. What date is your next period due to start?
2. "cum around my vagina"
   1. Do you mean vaginal entrance?
   2. How close to your vaginal entrance was it?
   3. Did any semen actually enter your vagina?

8 days after your period started would not be a fertile time if you have a typical cycle. 8 days after it ended could be.
