Not getting a positive OPK?

[nikki199013]

I started testing at CD 10, I'm now on CD 16 and the OPKs are darker but I'm still not getting a positive. I usually ovulate on CD 14. I had a chemical pregnancy last month. My cycles are usually 27 days long. Any thoughts? I'm really confused.
Tests are 20miu

I think that your ovulation date can change from cycle to cylce. I 've heard of people ovulating as late as CD 19. I hope that you continued to test after CD 16.

Since you had a chemical last cycle it's probably delaying ovulation. Are they getting close to positive?
