Is it possible to ovulate before LH peak?

Question

Based on my temps I would say cd 11 is ovulation day. 
I had a positive opk on cd11 but peak opk wasn’t until cd12. 
Any thoughts?

Answer

Yes it’s possible. Sometimes you could ovulate before a positive opk, during a positive opk, or after

Answer

Positive opk means you will ovulate in the next 24hrs which based off your chart that looks correct.

Answer

Strips dont have a peak. They have a positive or negative. Only Clearble Advanced tests have a peak. 
You got your positive on CD11 which makes CD12 your ovulation day. The FIRST positive is what counts.
