First month tracking OPKs

Hello - just looking for some insight as this is my first month testing with opk. I am going to also test bbt starting next month, but I didn’t know about that until I started reading more.

Based on the strips it looks like I had 3 days of high LH. I know you can’t confirm ovulation from the tests alone, but would you speculate ovulation occurring 12-24 hrs after the initial surge (CD 12) or the highest pe

ak (CD 14).

Thank you :)
