Can a drop of a fluid makes her pregnant?

I n my gf didnt had an actual sex(means i didnt insert my penis in her vigina) bt was still rubbing her vigina with my penis n as th fluid came out i moved away...i had a doubt that a drop of a fluid b left there on th vigina(but not inside vigina) is there isa chance she grt pregnant? Can a drop of a fluid makes her pregnant? She is also not having periods regularly...thanks
