TTC reading ovulation strips, PLEASE HELP

Emma

Hi. Please can someone help. I have 3 apps and all are telling me different days of ovulation even though they all have the same test result entries and period data etc, but I’ve been tracking with strips instead of digital this month and trying to get my head around when I’ll ovulate.

I used one clear blue advanced digital I had left yesterday that gave me my peak at 12pm too

and so tested a strip again today and positive. So does that mean ovulation will likely happen today or tomorrow?

FYI I’ve been testing for about 2 weeks and everything up until Thursday was negative and on another sheet so I haven’t added that picture.
