I am very stressed out. I really need someone to tell me everything is going to be ok. PLEASE! Here is the situation:

The other day my boyfriend was masturbating and ejaculated into a sock because he had literally nothing at the time to clean up with. About 15-20 min. later, he jokingly placed it in my hand for a second, but I moved it away quickly. Later that day, about 2 1/2 hours later, I went to the bathroom and touched myself a little bit because I was checking something (no, I was not masturbating, and no, I did not put my fingers inside of myself). When I left the bathroom, I started thinking about this and quickly went back in tried to wipe myself with soap, as I read it kills sperm.

Is there anyway something could have happened? This is probably close to impossible, but I have heard of women getting pregnant from some strange situations before. I don't see how this could have happened, as I looked at my hands after picking up the sock, and they looked completely dry to me. I also looked at them after the bathroom incident, and they looked dry. I also was driving between the time that happened and the time I made contact with other objects a lot. I was holding the steering wheel, holding papers, messing around with money, ect. I don't see how any could remain on my hand, but I am paranoid. I am sorry for this weird question.

Also, if it is likely that I am NOT pregnant, how can I relax and not stress over this? I have a history of getting paranoid and stressed out and delaying my menstrual period because of it. How do I take my mind off of this so that I get a normal period and don't freak out even more? I really don't want to stress out for weeks (my period is due the 17th), so I would appreciate anything that would help ease my mind.
