Need some advice

Last time I got equate ovulation they didn't work the best never knew if they were positive and I ran out. I do know that I ovulate but somehow the egg don't stick so I was going to try clear blue.

Do they work and how many times a day should I test so I don't miss it. We do bd every other day until I ovulate. But I'm not sure if I should track it so I have proof when I see the doctor if I don't get pregnant so I can find out why since it took 3 years with our daughter and I would like one more before I'm 40 which I'll be 37 next months.
