Still no smiley face on clearblue pink OPK. On CD 20 (top pic) I got the darkest line I’ve seen but no smiley. On CD 21 (middle pic) it got really light. Today CD 22 (bottom pic) it got a little bit darker again. Did I miss my surge or am I ovulating super late? Need to know if I should stop testing
