Last cycle I peaked on my ovulation tests at cd 17 and cd 18.

I am on cd18 today of my next cycle and it’s still very low.

I’ve been testing since cd9 this cycle and has been low every day.

Possible I’m just ovulating later this cycle than last cycle??

My periods tend to be irregular but was regular the last cycle and came exactly one month apart.

Any help?? Should I just continue testing daily? One app shows today is day 6 of my fertile window and another app shows my fertile window starts tomorrow.

Confusing!

Thank you !!!
