Hey! I tried the clear blue digital OPK this month (the one with either the blank circle or smiley)and got two smileys two days in a row, cd 14 and 15. According to GLOW, I was supposed to ovulate cd 15, yesterday. Does the smiley reflect ovulation or just a surge? I don’t do BBT because it’s too hard with night shift. I got a blank circle today so does that mean I’m officially 1dpo? And also, i BD cd 11, 12, 14, and 15. Are these decent chances for a BFP? Thanks!
