Hi, this is the first month I've tracked BBT, and been doing OPK also. I can't spot an signs of ovulation from my BBT, but my ovulations were getting darker and I did a clear blue digital advanced which showed Peak on CD 15. I'm now on CD 17 so thought I might have had my dip/spike in temp yesterday or today but haven't? When do you think I am actually ovulating?! Pics attached also, thanks!!x
