Hi I m Alisha, 21, and virgin. Since the last 2 hrs, i went to toilet around for 3 times.?

Does it symbolise that am pregnant bcoz i had with my bf for the 1st time around 3 weeks back. During the , his had some liquid..does it contain sperms? though he didnt go in me. And it was juz 2 days after the end of the periods for that month. Is there any possibility of me being pregnant? m really scared.
