So confused please read I need advice!!

Normally I’m very regular, peak on cd14

The last two months Iv struggled to Evan find my peak and only got a higher reading on cd12?? Not actually “high” just higher then the others that month…

I’m cd13 right now had ovulation pains on and off for about 3 days and still not got a high or peak?

Also I keep my tests and some look so much darker then what the app read but Iv been told you can’t add the in after 10mins?

Do you think it could be coming?
