cycle day 7 opk high fertility

Kelly
Hey ladies, I am on cycle day 7 and took a clearblue advanced opk this afternoon around 4:00pm and it showed the blinking smiley face for high fertility! Is this possible on cycle day 7 and has anyone else experienced this?!? If so did you get your bfp?!?! P.s. My cycles typically run between 29-31 days long.
