Hi Ladies !! Seeking some help here ... I have been using clearblueOPK & now currently on my 9th day of flashing smiley & according to Glow out of my fertile window. Last month my clearblue OPK was right on (2 high days followed by my peak & matched with my Glow days) anyone have similar situation? DH & I are BD'ing every night to cover our bases. I am just about ready to slap the smiley off it's face!
