Is this pregnancy?

I just need some advice...I am irregular and I had unprotected sex with my boyfriend 2 weeks ago...my last period was a week before that... I was a virgin when he takes me... Im really paranoid right now... I dont know if im pregnant or im just paranoid... How high is the possibility that I am pregnant? Am I fertile that time???
Help please

Okay, you need to stop having sex and learn about protecting yourself against these things before you do it again. Never have sex unprotected, ever until you are older and planning a family. You should have gone and gotten the morning after pill. Its VERY possible that you are pregnant. Its hard to say when you would have been fertile because you aren't regular. You need to go to your doctor and get a blood test done right away and tell him you had unprotected sex. You need to get tested for pregnancy, STD's, and also get put on birth control.

Go to planned parenthood and get tested...first...then get the moring after pill as a backup...I got pregnant on the reg pill so be sure you are ready to be a parent...that it is love not infatuation
