If you almost get into a car accident, but avoid the collision, is that still illegal?

I was getting into the turn lane a little late today, and the lady behind me was speeding through to get into the turn lane as well, and when I was turning into it she almost hit me. I realize it was partially my fault for turning in so late, but since she almost hit me from behind (hah) it would've been considered her fault for speeding and not paying attention to my turn signal, right? Well, she wrote down my plates and I'm kind of nervous about her calling the cops about it. Would I be getting in any trouble for ALMOST getting into a collision? I'm normally a cautious driver and I'm just worried about getting a ticket that I can't pay for.
