It's so frustrating!!

I have been opk testing since cycle day 12 and I am on cycle day 16 and still no positive opk. The lines haven't even changed at all!! I am testing 3 times a day at 10am, 3pm and 8pm everyday and still nothing. 3 years of ttc baby #2 is becoming hopeless. Even 3 months of clomid didn't work for me.
