Ovulation question 😞

Kristy
We've been ttc for almost 6 months now.  I've had cycles between 34-42 days long. This is my first cycle of using opks... I'm on CD 25 and still no positive... Anyone else have this problem? Should I keep doing opks? I'm assuming maybe I haven't been ovulating this whole time? This is such a stressful process... 😕
