Opk as a hpt?? Thoughts needed..

Rebecca • EDD 3-23-18 baby #3!
I know I'm probably grasping at straws here but have you heard of this before? I'm 9-10 dpo and this is my opk. I know hcg & LH are very similar and this isn't that reliable but it's interesting! I haven't tested with hpt yet. It's darker than I thought it would be. I have regular cycles of about 25 days. I'm cd 22 now. O'd on cd 12-13.  Thoughts?! :)
