Omegle.com: I start a chat with: "You're 18+", she writes "Yes"?

women from Asia, room qite dark. We chat, she asks me to show, I show. She doesn't show anything and disconnects. Now, a few days later i'm nearly getting mad since I wonder if she really was 18+. Could this have been a trap, trying to catch those pedos? Can they prosecute me for not being carefull enough? Should I have asked one more time how old she is? I know it was the most stupid thing i've done in my life, but i'm really scared, nearly going insane.
