If you are a virgin but have played around and thought you started your period 2 weeks late but it turned out to be just spotting could you be pregnant?

==New Answer Headline== Well, I know it sounds like the being a virgin part makes it impossible, but I know that there is a slim possibility due to some encounters w/my boyfriend of a year....I started my period 2 weeks late, like I said, but it's really irregular...it's way too light to be normal...and my period is ALWAYS normal...has been for two or three years...I just feel like something isn't right... no
