Opks not getting any darker…

🌼

This will now be my third cycle where instead of getting. Positive opk on cd 16, it remains faint, never getting a positive…

It’s literally been the same faintness this whole cycle. What is going on?? I tested 4 times yesterday (I know, a lot, but I just wanted to be sure I wasn’t missing the surge!) and here we are…still a very strong negative.
