fertile day one, plan B

Graciela
I had like two minutes of unprotected sex. He pulled out. First time doing it. I took Plan B later that day. When I looked at my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> app, it showed that it was my first day of fertile day one 9% chances of pregnancy high. I need help. I took it on Sept 8. Now it's Sept 13
