TTC while irregular

Ro

I track my period through 3 different apps. I have been doing this for about 3 years now. Check this out:

This one predicts ovulation on the 1rth of June.

This one predicts ovulation on the 8th.

Then glow predicts ovulation the saturday.

But, I had ovulation cramping on the 25th (CD18).

This is why I buy pregnancy tests in bulk.
