Whats my zodiac sign? Who doesn't mine quite fit.. at all?

I was never into astrology because my sign is supposed to be a Libra and it doesn't fit me. My best friend is a libra and her's are quite accurate to her. She borrowed a book from the library and was reading personality traits of some of the signs and I sound a lot like a Scorpio which confused me even more til my boyfriend at the time reminded me that I was born a bit too early as I pooped in my moms stomach so I almost killed us both. If I wasn't taken out early I would've been a scorpio. Is this possible? It just intrigues me so to those who know more about astrology if you can help me out, share some knowledge it would be nice =) I was born I believe almost 2 weeks too early.
