So we are TTC and I have been trying to pay very close attention to my CM. Tonight it was the stretchy clear kind and Glow says today is my most firtle day but my ovulation test says -no. Hubby and I went for it anyways tonight! What do you guys think is going on? This is my first time using ovulation tests and I have started testing since the beginning of my fertile window ... today is cycle day 15 & still getting -no!
