Second surge I NEED OPINIONS

KelCee

CD 22 was high , 23 was peak. Nothing before or after I was like okay that’s weird I usually have several days of high. . Due to my thermometer being crap I decided to continue my strips. Yesterday, (4dpo) it seemed kinda dark so I used my CBA. It was flashing. . This morning still flashing. .maybe I didn’t ovulate? Common second surge post ovulation? What you think?
