After trying for 2 years I started 50mg clomid this cycle.  Typically I ovulate on days 13 or 14. I have three eggs this cycle.  I've been using the clear blue digital and I've had a blinking smiley face for three days in a row in the past I would have a blinking smiley face one day and then the next I'd have a plain smiley face and then it would go back to a closed circle indicating low.  I'm currently on cycle day 18, how am I supposed to know what day I ovulated on? Has anyone had this happen to them?
