I have a pretty regular 28 day cycle (not perfect but close). But I get positive opk tests starting around cd10! Same with egg white mucus. What does it mean?? This past month I got my first opk pos on cd10, and did ici +8h, +25h (cd11) and +38h (cd 12). I had pos opks thru that time except the morning of the last ici. My temp was at its lowest at cd12, then crept up .2 degrees on cd13, and then another .5 reg today (cd14). What do you think? Did I get the timing right or was I too early? And now my cervix is really soft. Idk what it all means. I'm hoping I got it right. Hard to know how all the symptoms fit together.
