It depends on how you define "forplay".
If nothing was inserted into your vagina that could possibly have had semen on it, or if no semen came in contact with your body that could possibly have transferred to your labial area by hand or other method, then chances are slim to none.
So, if all you did was kiss and "pet" as foreplay, there is almost no chance. But if your definition of foreplay includes any ejaculate or pre-ejaculate (clear fluid from the penis that happens as a result of arousal) then it is possible.
When you say you were supposed to have your period on the 22nd, do you mean today?
That seems rather early to suspect pregnancy, but since pregnancy tests will detect pregnancy as early or earlier than the first missed day, there is no harm in testing to be sure.
Chances are Good. In fact you may already be pregnant, which is why you aren't having a period.
