ovulation? So confusing

Ti

I posted a few days ago that I am confused when I ovulate. I have three different <a href="https://play.google.com/store/apps/details?id=com.glow.android">fertility apps</a> and they all say something different. Can you look at these pictures and tell me when I should test for ovulation I am so confused. I took pictures from each app give me your best estimate. last two days I have had egg white cervical mucus but ovulation test Clearblue digital came back negative. I have been cramping up quite a bit last few days. And have been having intercourse as you can see in the picture
