You should wait until a couple of days after your period is due and if that comes up negitive, and your still worried of the possibilities then take a test every 3-4 days for the next two weeks. You can also go to your doc and get a blood test they can usually detect preg as early as 10 days after conception. Good luck let me know how things go.

Hehe...Lee already said what I always say.

And I suggest u that next time u have unprotected sex (if u really really have to, dont if you dont have to), the next morning, u should go get the morning after pill to prevent the pregnancy fear
