I had my first cycle in 3 months (wasn't pregnant, but had HA) on Dec. 1. Started using an OPK on day 9, and have received 8 flashing smiley faces...  According to Glow, I should have ovulated on 12/13. I felt a lot of cramping and could tell a change in my CM, but never got the solid smiley face... I am on CD 21 and got a flashing smiley this morning... Anyone else experience this?
