What am I doing wrong?!?!

Hi, I've been using glow for a little while now, but this is my first post. The reason I am posting something now is because my husband and I are trying to conceive and aren't having any luck. I have taken ovulation test but they say I never have a high LH. I don't know if it is because I am testing on the wrong days or not. We have been trying for around 2 months now. My husband is starting to think there is something wrong with his sperm. I don't know what I am doing wrong. Can you fellow glow users please help me
